I agree with sukmy. But also, for me, the look is an adjustment (although I find it looks great) but the feeling of two smooth shaven guys' skin rubbing together is so hot! That hair robs your skin of so much sensitivity. When a guy is smooth, it's so much nicer to explore every inch of his body with your mouth -- kissing and sucking and licking till you find those certain spots that just drive him nuts! It's nice and clean if you are the one giving oral, and because the guy getting it is getting to enjoy the full sensitivity of his skin, the tactile response is amazing!
IDK, to each his own, but don't knock it till you've tried it!
