Okay, so i have dated and slept with male and females. To me girls give way better head, but it may be that the guys i have been with just like rough and hard sex more. The sex in all is very "Filling" but as a Nude model in the Adult Industry, i've seen lots of different position and thrust types, as a guy or girl, is it a turn off if a girl is "Flexible" and knows lots of different positions, sometimes knowing more than you....?
