I don't know, I think it looks kinda weird when a guy shaves his legs/arms to be honest. And I think some chest hair is sexy. Now if a guy is starting to look like the wolfman, it's probably time to break out the razor, especially if he's growing a rug on his back. It's really never bothered me though that I shave my legs, armpits, and feminine area and my husband only has to worry about shaving his face.
