This is just my own personal opinion.
My guy has an athletic build, but he's a slim athletic guy, not a big bulky one. He's one of those guys who never grew chest hair, like a Native American. He has about a dozen small fluffy hairs around each nipple and that's it. I think that's one of the reasons why he doesn't look odd to me when he goes bare. I think it only took me one or two days to get used to him without any hair and I prefer sex when we're both bare.
I prefer him either natural or waxed/epilated. I'm not a fan of shaving because of the stubble. Waxed and epilated hair grows in soft.
