On the rare occassions I do let my fiance shave me. I rather he did it so I wouldn't nick myself.
"Sexual pleasure in woman is a kind of magic spell; it demands complete abandon; if words or movements oppose the magic of caresses, the spell is broken."
Simone de Beauvoir
I've only ever had one man shave me and I loved it. I'd have future boyfriends do it too. It's fun to do with another partner. I use to shave him, and he me. With me though it always got sexual. I guess once he was down there he couldn't help himself. xP
I could see that being very erotic!
