Stop faking it, first of all. That helps neither of you.
Satisfying sex requires good communication. You have to let him know your limits, what feels good and what doesn't, when to stop, etc... and he has to do the same. If you both can't communicate what you want during sex, you just shouldn't be having sex.
>>2 is absolutely right. I agree completely with that. Basically, communicate! The most important part of a relationship is also essential during sex! You've pretty much got the same answer from a virgin and from someone with experience, so that says a lot.
