I've had experiences with boys being selfish in the past, unfortunately my ex was like that. I don't know whether he did it on purpose or if it was lack of experience, but a lot of the time it left me very unsatisfied and unwilling to be even remotely interested in sex. Not only that but I felt he thought some things were owed to him.

But recently, there's been a man (and I stress man) in my life who's showed me that not all men are selfish when it comes to sex and foreplay. And I owe him a lot for it =) So I think it's more inexperience that leads people to believe that men are selfish. But you know, I know a couple women who are only interested in being satisfied but not satisfying their partner.

And I agree with Osuche. I can't openly say what I want, I can try and show him, but that doesn't always work. So I think maybe that if that's the case, then it's not necessarily anyone's fault. You can't help it if you're shy about telling someone what you want during sex. And it goes for both men and women =)
