...it's certainly not a problem with my partner. I can totally understand how a girl might feel inadequate - "Every guy orgasms during sex, right? Usually too quickly, haha..." - but from my own experience, I'm chalking it up to a combination of:
- Every guy is different; it stands to reason that some guys will orgasm more easily than others. Premature ejaculation must have its counterpoint!
- Condoms suck. I find it easier to orgasm without one; they're tight in the wrong areas and I suspect they can restrict bloodflow to some degree.
- Getting the right position! Missionary can suck because it's tiring and the angles are quite forced. Doggy style is often good because it can be a team effort, and penetration is usually deep. One girlfriend was much shorter than me, which meant that anal sex actually gave the best angles for pleasurable sex - but that's a poor excuse for pressuring a girl into experimentation!
- Mental issues. Personally I overthink things and find it hard to get totally lost in the moment (no matter how much fun I'm having).
I find it easier to orgasm during oral sex, easier still through masturbation. That's largely a matter of being able to easily hit all the really great-feeling spots. Orgasm during intercourse generally takes a concerted effort, and often it's more fun not to really try.
I've found so long as I *talk about it*, make it clear that this isn't a problem I have with the relationship - physically or emotionally - then we're very happy. It's actually nice to be able to enjoy having long periods of sex with someone I care about!
[Edit] And I can assure the previous poster that I, at least, am not gay. Orgasm isn't the only measure of a guy's excitement - so long as he seems into you in other ways, you can ignore your paranoia. If you relax it will probably help him, too.
