Now if your other mobile phone was to ring or you had to scratch whilst in the middle of a conversation on the first mobile you would have to let go of what you were hanging on to, which would cause your journey to end. Knowing how to land correctly would be vital to your survival. I have also been told stories about people putting their feet on the tracks and holding onto the back of the train, known as train surfing. This would surely kill you. Eventually. You mention that this might be dangerous, but I propose that after learning these instructions it is safer than jumping on the bed 8230at least for me. When I was 8 years old, I was jumping on my parents bed showing them how I could do the gymnastics moves they were watching on the 1988 olympics. I had not been taught how to safely jump on the bed in school (yet another terrible oversight), so I didn8217t know that step 7 for jumping from a train also applies to jumping on the bed As you may have guessed by now, I was laughing while jumping on the bed. as I came down to jump again, my knee found itself underneath my chin while my head was rapidly descending. My jaw obviously closed, and, well, my tounge was in the way. 3 hours, one trip to the emergency room, 7 stitches in my tounge, and an average crying level of 96dB SPL (A weighted), I had my tounge back in one piece. But pay special attention to step 7 above, because if you8217re jumping from a train you8217re likely farther from an emergency room than I was at home I can verify that train surfing can and does take place. I would have seen it going on in Germany. But the dangers of train surfing became all too apparent to me one evening when I was waiting for my S-Bahn home. There I was waiting for my train, trains coming and going, no big excitement. Then I heard someone whooping and hollering. I looked around to see some dude hanging on to the back of the train. He was kinda hanging out the side at the back and seemed to be having a mighty fine time of it going his whooping and hollering, never mind the large grin on his face. Anyway as the train picked up speed, I duno maybe hadnt thought it throught, but as it pulled out of the station, all the time picking up speed, and as the platform got shorter and shorted for him he had to make a decision. Hang on or jump off.he jumped.wrong decisionhe went head first into an all too stationary pole Not a pretty sight. Good news is that he survived but the bad news is that he both shat and pissed himself, as a result of the impact or from fright I dont know. And here is a wonderful photo to go along with this post. I am an avid cliffbridge jumper. I have a dream to jump off of a moving train at a local swimming hole, where the railroad bridge crosses the river. Has anyone heard of anyone attempting anything like this The train usually goes 40-50 Mph across the bridge, and the river is 50 feet wide at best. I need some more input on this before I even think about attempting. Help me if you can.. Dude, you8217d miss the river for sure. Don8217t try that. Plus, hitting water at that speed could kill you. Train Hopping 1974 In 1974 I hopped a freight train for fun and adventure with a young man, Eric, who I had met that afternoon. He was my age8230mature teenagers. We were bored hip-kids living in Ashland, Oregon. We found a ride into the next state, California, so we could ride the train back home. Once In the train yard we climbed up and held onto the ladder nearest a open boxcar door. After the train started moving faster8230 Eric determined that it was 8220going the wrong way.8221 It was heading south from Dunsmire, into California. He said, 8220Jump8221 and he jumped. He landed feet first and running with the direction of the train. I had a split second, as a girl, to either jump or ride alone. I had no pack, of course no cell phone, and was dressed for summer weather. The seconds that passed between his command and my decision resulted in a much faster train speed. It had also greatly increased the distance traveled from him. I chose to jump. I jumped as though into a swimming pool. I had no idea what else to do. I simply said, 8220God, please help me.8221 I hit the gravel and hard dusty berm below with an impact. I8217m guessing the train was going about 18 mph. I rolled and tumbled like a cartwheel and finally landed on my butt8230upright. I began to cry. But not wanting to appear like a baby, I pulled myself together, stood up and said, 8220It8217s OK. I8217m alright.8221 At that age, I didn8217t realize the gravity of the danger of what I was doing. I could have died that day in numerous ways: a door sliding shut on us, my clothing getting caught on something, a broken back or neck, or fell under the wheels. Please read the advice, everyone, about these very real dangers. I don8217t know why I was unharmed, God had a plan for my life I suppose. As Providence would have it, we both brushed ourselves off and reboarded a train with an open boxcar that was starting-up for Northbound towards home. The trip back was an experience of wonder and beauty. We didn8217t speak much, we just wanted to get back home8230 safe. As we wound our way far from the highway and towns we found ourselves passing areas that only can been seen by rail. The sun setting casting an orange glow on Mt. Shasta8217s snowy top was stunning. We passed a waterfall that flowed under the train trestle. The train climbed slowly over the Siskiyou Mt.s as the sunset turned into a cobalt blue star filled sky. Chilled, we just huddled in the boxcar door trying to stay warm. When we arrived in Ashland the train slowed at a crossing and we simply stepped off a block from Eric8217s place and I walked home a short distance away. Later, a friend remarked, 8220Where did you get this Levi8217s shirt. It looks like it was mauled by a lion.8221 It was the shirt I was wearing that day. No blood but the back was shredded. I would like to mention that my Great Grandfather was a Colorado Railroad man during the Great Depression era. He was not a conductor but a professional rail supervisor. Perhaps his spirit rode me that day. I never saw Eric again8230he was traveling through and we lost contact. I was in Oregon just for a summer. The memories remain in my mind like faded photographs. Today, by an act of Congress, train hopping is a federal offense in the USA8230.and don8217t forget it And, don8217t forget my brush with death on that beautiful California summer day. I was very fortunate. Next time I want a rail journey I will simply buy a ticket and view the scenes from my window while reading the history of train-hopping. Q: Alan is travelling on a freight train which is moving at 43 mph, and his friend Jeremy is on the opposite railway travelling towards him at 27 mph. Assuming that Alan had a breakfast of eggs and orange juice, what is the proper roll technique he should use to avoid injury A: Alan probably could have used just about any rolling technique without injury cause alan wasn8217t jumping from a train. He8217s still on the freight train. It didn8217t say anything about Alan jumping from train. If he was a vegatarian. He might of puked from not eating flesh(eggs) for awhile and puked on jeremy at insane 70mph. Jeremy could of fell and hurt(injury) his back from the massive force of Alan8217s vomit. Then the only thing hurt(injury) is Jeremy8217s back and feelings cause he didn8217t get chill with Alan. Having jumped off a freight train I can attest that this article is pretty spot on..

Write a CommentPenis size is an important matter to many men, so its natural that you may want to increase the size of your penis. But the question is how to do it and what to use If you are looking to increase the size of your penis or improve the hardness of your erections youve probably done a little research online into the methods that you could use to achieve your desired results. Usually, a search for male enhancement will suggest links for penis pills, penis pumps (vacuums) and penis stretchers, but you may not be aware that penis pills and pumps will not actually increase the size of your penis. There is a lot of evidence behind these points, but the ineffectiveness of penis pills is a topic beyond this article as there are many aspects to consider. They may result in better erections or a temporarily larger erection, but in actuality, the only way to permanently, effectively increase the size of your dick is to use a penis stretcher. Which is the best penis stretcher to use If youre set on the idea of increasing the size of your penis and you understand that using a penis stretcher is the best way to go, its time to take a look at whats on the market and decide whats best for you. However, to save you the time and trouble of reading countless descriptions and reviews on various products, why not read on to learn more about the Phallosan 2 in 1 Male Enhancement System This device is different from other penis stretchers on the market. It is specifically designed to both improve your erections and increase your penis size through stretching. But what makes it stand out amongst similar stretching devices is its unique design. But whats so unique about it The Phallosan 2 in 1 Male Enhancement system combines the technique of a traditional penis stretching device with the extra added power of a vacuum pump for optimal enhancement. Could this be a good thing or a bad thing Lets find out. As the Phallosan 2 in 1 Male Enhancement System combines two effective penis enhancement and enlargement methods, men who choose to use it are increasing their chances of getting better results and a faster rate. The vacuum suction element of the device will improve blood flow to the penis which will help to ensure bigger, better, stronger erections, whilst the actual stretching element itself will be the most effective aspect, helping to increase the penis size permanently and significantly. If youre wondering how a penis stretching device works, it will create tiny tears in the penis tissue which triggers cell division and natural penis growth as they begin to heal in their new, larger form. Dont worry the process is entirely painless When compared to other penis stretching devices you may have used in the past, the device is bigger and heavier, so the idea of wearing it under your pants is unlikely to work out. Penis stretchers need to be worn daily for at least 30 minutes, so its important you have somewhere you can commit to a stretching schedule. As it is difficult to wear the device unnoticeably, the device will need to be worn at home. If youre busy with long work hours or social commitments, this can be a significant downside. Is the Phallosan 2 in 1 Male Enhancement System right for me If youre hoping for a larger, better looking penis with stronger, harder erections leading to a better sex life, the Phallosan 2 in 1 Male Enhancement could be exactly what youre looking for. By going directly to purchase a device that you know is a cut above the rest, youll be saving yourself the trial and error of finding something that works for you. If youre at home a lot and have no issues wearing the Phallosan on a daily basis, youll be just fine. However, if youre often outside, meeting with people, walking or exercising, the Phallosan device may be too large for your lifestyle and another stretching device could be a better option. Its clear to see how the Phallosan 2 in 1 Male Enhancement system could be beneficial to any man looking to improve the size of his dick and experience better erections, but of course all benefits come at a price. If youve weighed up the pros and the cons, chances are youll have a clear idea of whether the device is for you. If so, order it today and take the first step towards better sex.

Many men think that a large penis means youve got it made and all the ladies would LOVE to get in on some of that action. This is a false way of thinking. Although not all men with bigger penises experience these downfalls, here they are. It Doesnt Fit The truth is that a womans pleasure canal is only about 5-6 inches long when theyre aroused.

Women are MUCH less likely to give oral sex if a man has a large penis. Its Painful If their penis is too long, it will repeatedly hit a womans cervix (the end of her vagina) which is an extremely sensitive spot. So IT HURTS. And if its too wide, it will stretch them out and thats also quite painful. Its Intimidating Its true Some women take one look at a very large penis and immediately are just scared.

While it may seem a little risky, some men have even managed to control their ejaculation so well that they can have safe sex without having to use a condom helping to improve their sexual experience through increased sensitivity and the touch of your partner. Whichever of these methods you decide to try out, you can rest easy in the knowledge they are both free and safe for you to test out as much as you want.

There are more than 100 penis extender brands available in the market and choosing the best one could be a tedious and very long process. Browsing and comparing each one can take up many hours of time. Not to mention the advertising and extra marketing material found everywhere you research, finding a legitimate and honest feedback is nearly impossible. Its not easy to differentiate between various penis extenders to discover the one which is actually the best. By performing a careful search on the market, you may find these brand names: SizeGenetics, Vimax Extender, X4Labs, Proextender, Euroextender, Ultimate Stretcher, Jes Extender, Maleedge, etc. Following are some things you should consider before buying a penis extender: The first thing you should consider is the ease of use. A penis extender must have a comfort mechanism which should allow you to wear it with comfort and ease all day. Ease of use is very important because for better results the extender should be worn for as long as possible. Thats why, it is critical that it does not cause any issues that could interfere with your lifestyle and daily routine. In this modern era, you should consider pure facts, evidence, and real testimonials before buying a product, not claims. Therefore, go for a penis extender which is clinically supported by research, number of trials, and has been recommended by doctors and other health experts. It should be clinically proven to enlarge your penis as well as improve overall sexual pleasure and performance. A best way to verify credibility is to look at penisextendershq and check whether the product has been certified by health care providers and recommended by trustworthy medical practitioners. Keep in mind that an extender that works naturally should be your preference. A natural penis extender should have two features. First, it should have a powerful traction to stretch the tissues of penis in a natural way and induce 8220division and cell manipulation8221 resulting in a natural growth of the penile. Secondly, it should maintain the erection of penis for a long time by drawing blood to the tissues of penis. In simple words, if above mentioned features are available in the extender, then thats the mode of working you should be looking for. A penis extender must be tested for potential hazards and potency and should be backed up with the latest science and research available. Additionally, a good production source or facility is a major factor in guaranteeing the best quality . Therefore, always look for trustworthy brands that have been around in that business for some time to make sure what is labeled on the product is not only safe but also exactly what is featured in the product. There are various brands rated by PenisExtendersHQ that are reliable and have presented significant results of penis enlargement. Thats why, you should never compromise for less quality. Just because a manufacturer says a product is natural doesnt mean it is safe. Thats why, you should do your research before buying a natural penis extender. Carefully read the authentic testimonials and check whether the product has been certified by a global and reliable authority on health. It should have a high safety profile. Ideally, it should not cause any discomfort or skin marks after a long term use. Additionally, user tolerance and compliance is a major problem you should consider while buying the best penis extender. Generally, all penis extender brands claim to have no side effects. It is true if you are talking about the top brands because they actually dont have any side effects and are safe to use. Careful use of the product is another factor as you should take caution when using it. Most extenders are only required to be used on the penis for maximum of five hours per day. If the required time to use is labeled on the product, then you should not use any longer than that. There are many high quality penis extender brands available in the market (mentioned above). But personal research and careful inspection is necessary to get the most out of them as well as avoid any issues. All things considered, buy the one which is not only free from side effects but also viable. A 100 effective penis extender should help you achieve a thicker and larger penis as well as should produce longer and stronger erections. When you look at the number of stores and websites selling sex toys, not to mention the size of most dildos on the market, it can be a little unnerving. Men may begin to feel as if their penis simply cannot compare to the size of the dildos their girlfriends or wives may use on a regular basis. If youre afraid that you could be replaced by a sex toy, its time to take a look at which really works the best for sexual satisfaction: a small dick or a big dildo Women often say that the size of your dick is irrelevant and that may be true to an extent, but at the same time, she will of course value her sexual pleasure too. Theres a reason most dildos on the market are on the larger side, and thats due to demand. The manufacturers would have no need to make those products if they werent likely to sell, so obviously women are buying them when they visit sex stores or websites. Dildos on average range from around 6 7 inches long to 15 and beyond, and are usually very girthy. In comparison, your dick may look a little on the smaller side It can often leave you wondering whether longer and thicker are really the key aspects that women want to see in their partners penis. In the USA alone, over 50 of women admit to owning and regularly using a vibrator or dildo. Women who enjoy such toys may become used to them as time goes on, only to be left disappointed when faced with a realistic penis. Women also enjoy the fact that a dildo will never come first the fun doesnt stop until shes ready. The short answer is YES Whether your dick is large, average or even on the small side, you can ensure it can compare to a dildo even of the larger variety. First, youll need to work out exactly what you currently dislike about your dick. Is it too short Too thin Do you ejaculate too soon Are your erections weaker than youd like No matter what the problem is, there is a way to resolve it. So which really does work the best Honestly, while women may love the feel of using a large dildo or other sex toys, they are likely to choose a real man over plastic any day, as long as they are attracted to men sexually. If they dont like real dicks of any kind, you dont stand a chance, so you should probably look elsewhere. If your partner loves you andor finds you sexually attractive, she will feel pleasure from your dick and enjoy having sex with you instead of a toy especially if youve taken the steps to boost your penis size and sexual experience. There are a number of ways you can ensure your penis is worthy of comparison to your partners dildo. Why not try a few out and see which works the best for you Penis Pills . The term penis pills refers to male enhancement products that aim to improve your erections and create a positive, satisfying sexual experience. They are also known for boosting your libido. However, although marketing alongside products that may enlarge your penis, penis pills will not have that effect. Herbal Supplements . If your problem is that you come too soon during sex, there are certain herbal supplements that may be able to help. Take a look around your sexual supplier of choice and ask for their help if necessary. Penis Pumps . A penis pump, also known as an erectile dysfunction pump is a device that will help you achieve harder, healthier erections and last longer in bed. While your dick may appear bigger during use, these effects are not permanent. Penis Extenders . A penis extender, also referred to as a penis stretcher or stretching device is the only way that you can effectively and permanently increase the length, girth and overall size of your dick. These devices gently pull on the penis using traction therapy to stretch it to the desired size. Whichever method you choose to improve the size and shape of your dick, your partner will certainly appreciate it and youll find yourself proving to be better than the dildo every time.

According to the British actress Maureen Lipman, the worst part of oral sex is the view. It is one of the many reasons why a lot of women dont want to perform oral sex with their lover. The view only does not turn them on. But most of the guys do want to have oral sex with their partners. If your girl always makes excuses or hesitates to perform oral sex and avoid giving you head, it might be due to many reasons. So it is recommended to first know what those reasons are. Following are some reasons why your girlfriend is not giving you oral sex: She thinks that oral sex is mostly done by prostitutes and its disgusting and degrading. She doesnt want to give you oral sex because she might be thinking Whats the point of putting in an effort in a thing which is not worth it. She has no experience of it and did not gave anyone the oral sex before, and shes scared of embarrassing herself and making an oral sex failure out of herself. She is too doubtful, maybe she has no self-confidence so she feels disappointing, maybe shes overweight or thinks that she will look stupid or silly when giving you oral sex. She is bad at giving you the oral sex, many people just dont like doing something they are bad at Your penis is either too smelly or too hairy, and you she doesnt find you attractive at all because you dont take care of yourself and other girls also find you unattractive Giving you oral sex does not turn her on because beg for it, ask her to do it, and put yourself in a lower position in your relationship. Cheap persuasion strategies and bribes rarely work (if they ever do). Usually those tactics result in even less oral sex. She has no clue how important giving oral sex for you is and she has no idea how a good oral sex can result in a better relationship with you. And you dont know how to persuade her to give you oral sex by rewarding her whenever she does what you want (gives you a good oral sex) Most of these reasons can be easily tackled by following the steps mentioned below: Its easy to solve the first thing (her considering oral sex disgusting and only reserved for prostitutes) by being as open-minded as possible. If she feels that you will see her as less valuable if she talks dirty and simply goes and sexually enjoys herself, then she won8217t do it. There is only one way to motivate her to let go and enjoy the sex instead of feeling pressured during it is by being completely confident and relaxed. Love her entire body and kiss her everywhere. She should feel that you accept every part of her. Shower, shave and groom. Your penis has to be welcoming as well as spotless. Next, you have to become more attractive to the society. Hit the gym, get a higher status, get a better job, get more social power and friends, make more money, and make a hobby of traveling to exotic places. All this contributes to you being more valuable and interesting. Quit sitting in front of the TV all day and do something interesting with your life. Build up your confidence and try to perform better in bed. All this will make oral sex more interesting to your girl. Something else you have to do is be as non-judgmental as you can. She needs to know that you will not in any way think less about her if she gives you bad oral sex. And you wont break up or dump her. Tell her that she can practice as much as she wants on you and try to make oral sex more fun to her instead of making it a chore or job. Dont try to avoid the issue. Simply tell her you want her to give you oral sex. Gently tell her if she gives you the oral sex, you will really appreciate. Remember not to force it. Let her take control of the situation by starting slowly. If she does give you oral sex, then its important that you keep the communication alive during oral sex. Send feedbacks through body language verbal communication.
