I shaved my legs once and hated it. Never did it again. I used to shave under my armpits too, but I don't anymore. If I have to go swimming or change for PE, I just keep my arms down.
My friend asked me why my leg felt hairy one day while I was swimming with her. My leg had brushed up against her's, and she was like 'Shave your legs!'. She's aware of my 'manliness'

but she doesn't know I'm trans yet because I'm to afraid of what might happen If I confirm her 'jokes' are true. Anyway, I could care less that people think I should shave my legs. But when I finally get my surgery, I think I'll keep my chest not hairy, because that's just creepy to me.
My armpit annoys me, though, cause I don't have enough hair to make it look ok, so it just looks weird. But I guess I don't really care.
