Well, it really depends on how the person looks all over and what the chest hair looks like with it...
I actually do find it pretty gross on a lot of guys, but guys like Norman Reedus I'm totally cool with having chest hair. *shrug*
My first real exposure to pornography was yaoi, in which most guys are depicted without body hair, soooo... I think it maybe brainwashed me into not liking body hair, which is a very unrealistic expectation in real life x_x I'm doomed to be forever alone due to my pickyness.
Edit: I just realized I bumped this thread x_X I went into it from someone's profile, read through it, and forgot about that... Yeah... At least it's not too old.
