My opinion manscape that thing fellas.
It wont stop me if you're not, but I may not spend as much time doing oral. I dont need or want any hair in my mouth, and I dont wanting tickling my nose when I'm down there. Not to mention, it just looks better. Looks clean and inviting.
I like some hair on the chest and maybe a little on the belly, but if you've got hair on your shoulders, back, or balls, I'd prefer you get that removed.
