Now some women love what gays would call Bears. Bears are guys who are covered in a thick layer of hair everywhere. Personally, I see a household that has to invest in loads of drain cleaner if your guy is a bear.
Actually, most hair goes down the drain, even the hair from your head if you keep it reasonably short. Our hair is always falling out and, if you're not suffering from male pattern baldness or some other ailment, it's constantly getting replaced by new hair cycles. The clumps that form in the drain are usually due to someone who has long hair, probably on their head. It doesn't go down so well. I learned this from when I had a roommate in college with long hair. He had very little body hair. I never find hair in my drain, the one that no one else uses. Whenever I share a restroom in a household with people with long hair, I find I'm having to perform that most distasteful task of plucking out that wet clump on a regular basis.
One problem with body hair is it's a breeding ground for the bacteria that causes body odor. Sweat has no odor. It's the bacteria that grow in it that create the odor. It's probably not that much of an issue except in a few key places like the underarms, crotch, and butthole. That's where the really nutritious (to bacteria) extretions come from. There is actually some musk that is our own scent that hair has nothing to do with but that's actually not the same smell that most associate with body odor. If you're bushy in those areas, you can go a long way toward controlling your odor between showers by just trimming it; yes, even guys. One of the reasons women tend to have less body odor issues (American women, anyway) is that most shave their underarms.
I'm actually really on the low side when it comes to body hair, for a guy anyway, and I still trim the key areas. I think it helps a lot. But then I'm gay and I don't have weird issues about grooming that so many str8 guys do. It's not a threat to my masculinity.
