A noisy girl means she enjoys it, a noisy guy is just awkward and distracting. There is a reason why, It's the natural order of things. I don't mind grunts and moans during sex from my partner, but if he is louder then me, then I am going to get distracted and not enjoy it. Guys base how well they are doing on the noises a woman makes. I could be quite, but he knows how to move with my moans, and bases how well he did on the moans and groans. There is a reason for this statistic to be the way it was. We are different breeds needing different things so therefor we also react differently. I also can multi-orgasm and he can't.
