I can't stand hair on a guy, especially on his chest! :gag: I like a clean shaven guy... except when they shave their armpits. I think that looks TOO feminine. So I prefer it if he just keeps those hairy but trimmed nicely. 
In some cases however, if a guy has a really nicely trimmed happy trail....i'm not opposed to that either.
As long as i'm not diving into chewbacca-land! lol
