Pre-T here and I think I've got more than the average female-bodied person who has boycotted razors. XD I'm blonde, but for some reason all my body hair besides that on my forearms is brown, and there's a lot of it in my pits and my lower legs, although strangely it's sparser on the outsides of my calves...weird.
I stopped shaving my pits a year ago because I kept getting ingrown hairs from shaving. I have to say deodorant is actually more effective now and I sweat less there. More hair and less smell, who knew? I do trim it a bit every month or so though.
