How much are we talking here? I'm not going to lie though, as a straight male even I find full on man boob repulsive. It would be like seeing a woman with a full on goatee, it just ain't right.
They're called "moobs" and for most of the most part, not me. Unless they were slight and hereditary or the guy was otherwise incredible. (Like men on here don't rate women by numbers... 8) )
