I still do not understand why you would do that to yourself. The point of sex, is not to last the longest you can, but for both people to enjoy it the most they can. Unless you're keeping score, from a third person point of view, you should also be enjoying sex. I know many people who will dread over the idea of having sex, and not enjoying it at all. This problem is very common in women, who have sex with their partner only to see them orgasm, and then stop sex completely. This is very frustrating to women, who will not admit the problem to their partner directly, rather share it with friends or keep it to themselves. I have met many women who talk about sex with their partner and begin to cry at the mear thought of it. I have also met men who do the same. You have to ask yourself. Do you want to be someone who enjoys sex, and doesn't think about holding back, or do you want to be like those men who have sex and do not enjoy it at all. My cousin has told me that he has had sex with his girlfriend, and out of the 8 times, he did not ejaculate once. I must say, sounds like nothing is wrong, but he was furious. After sex, he became silent, and very emotional, he even started to cry at the thought that he was about to finish but he was simply left hanging, so to speak. Is that really how you want to remember the sexual history between you and your partner? I believe that you should stop think how long you can last, and try to enjoy sex as much as you can. If you feel that by lasting longer, you are giving more pleasure to your partner, you might be wrong. I do not last long at all myself. Yet, I find many ways around this problem. Even when i'm done first, which is almost always, I force myself to take the time and make certain that my wife gets the same pleasure from me. It's all about keeping a healthy balance, and if you do, then there is no reason to worry over who finishes first.
