Clean and Tidy
Both of my men shave down there. They do it themselves with a really good electric shaver. So it's not completely bare like a boy, but it's just clean and tidy. Which, does make oral sex nicer. (IMHO) My BF is just a hairy guy in general though, so his wife helps him shave his chest and back. Two reasons for that. First, he's a bit self conscious about it. (though I find it sexy!) The other is that he gets massages periodically to help with stress and the hairs tend to pull during a massage. He never shaves totally clean though.
