Sorry, I have to voice my opinion (you may not like it, but opinions are like assholes, everyone has one).
There are some ladies (like me) that are out to please a man during sex. I ask the man what he likes, how he likes it. I want the man to tell me what feels good and what don't. BUT, I also expect that in return. I've had men that SUCK in bed just because they think all women are the same or they don't communicate and ask what feels good or how they like it. Turn abouts fair play.
As far as us women being selfish...I believe men are selfish. Most men (whether or not the woman SUCKED as you're trying to state) a man gets off and that's it. Very few men try to please a woman. I work my ass off to do what he likes and how he likes, whether it be sucking his dick, fucking, or whatever just so he will enjoy himself. I would rather please a man than have a man please me (don't get me wrong, I LOVE it when a man tries to please me).
Do you understand what I'm trying to say? That not all women are selfish and don't try to please a man and try not to "SUCK".
