Come to think of it, there was a picture a couple years ago or so where Shannon Seeley was wearing a slight goatee, but I've never been able to find it since.
Wnat was her name?
Actually, it's quite common for girls to have nipple hair. What they choose to do with it is their decision. Back in my working days, I'd often jokingly challenge pretty co-workers to drink some exceptionally strong black coffee or eat something exotic with the exhortation, "Aw, c'mon, it'll put hair on your chest." You'd be surprised how often they would giggle and say, "I already have hair on my chest."
I seem to remember years ago pictures of some big strong gal on Saradas who had obvious beard growth going, but I sure can't remember the name. Then there's the pictures of Saiborg Brasil where she's sporting a full goatee.
