Is your man or woman loud or quiet during sex? If your partner is the quiet one, does that bother you? Why??
My partner is more of a "noise maker". Now me on the other hand, I like to talk dirty. I don't pretend to make noise, just to boost his ego, either.
I'm the moaner (well they can be pretty LOUD moans sometimes, hehe) and he's the talker. I would hate to have a guy who was totally silent in bed, that's just like you don't get any feedback. Might as well fuck a teddy bear. Sounds in bed are such a turn on, and it shows you what your partner likes or not, so it's really important.
