My girlfriend had been interested in straights enough to let me shave her legs this weekend (she was the one who suggested it :D ). Anyways, I'm wondering if there are any tips for shaving someone else's legs. I'm proficient with my own face and I've done a few other faces so I'm a little bit used the lack of tactile feedback. Do you suggest using anything as far as aftershave? Any particular angles I should be careful of?
