well maybe your too good at what you do, or he has premature ejaculation. this is a psyhcological problem. Your boyfriend or sexbuddy or whomever can go online and look up some ideas on how to not come so quickly. try diffrent postions so it dosent stimulate him as well, try having slower sex so its not as intense for him.
vmlovergirl, He has to deal with his premature ejaculation himself. You cannot do it for him. It is normally very difficult for the guy. He is not doing it on purpose and cannot help himself. You can point him to this thread on here: http://ehealthforum.com/health/topic86215.
When this is the case, there should normally be an understanding that you orgasm before intercourse. Either with fingering or even better, oral sex. It is important that you deal with it. If not, you will end up being unhappy and dissatisfied. You have the same rights than him to enjoy sex and orgasm.
i agree with talking to him, but do it nicely, men don't like their egos to be destroyed in bed or if you don't feel comfortable talking to him you could try more foreplay for you, and try a position you like. sometimes being on top helps because you can control what your doing and how to please yourself
Try some sta hard cream to prevent premature ejaculaiton
You can also try a de-sensitizing cream. I like STA-HARD cream. You can just buy some on line and rub some on him as part of your foreplay. Communication always makes sex better but there are some simple over the counter things you can try before you insist he start downing cialis.
If he comes before you, give it a break, explain to him, and usually the guy is ready for round two. It's proven that it takes more effort the next time, which means he will last longer. So you'll have more of a chance to get that orgasm!
