In my somewhat limited experience I have found that men are better than women at giving BJs. (Some) women have no clue whatsoever, don't know what to do with the thing. Other women look at it like war: hey, you want a BJ, I want oral sex. Give and take. But then we know that even if a woman takes excellent care of herself, pussy is pussy and it stinks. Guys know about dicks, know how to handle it and themselves. of course it may also have to do with personal tastes....a guy may prefer to be served by the lips a man......then *** and explode where it matters.
