As far back as I could remember in my sexually active life, I've gone down on every woman who I've been intimate with. I enjoy eating pussy, and really enjoy watching her squirm, gasp, and moan when I make her come with my tongue.
Now, I've gone out with one or two women (back before our swinging days) who refused to go down on
me ("Ewww. You want me to put my mouth on it? The same thing you pee with? No way!") Those relationships tended to not last very long for other reasons, but I'm sure the entire no-blowjob thing might have had been a factor.
ATAK said something along the lines of "for recreational sex, if it smells funny, I ain't gonna lick it!" That's understandable. But if it smells that bad, I ain't gonna stick anything in it either!
