I've avoided this topic because it got the replies I thought it would.
I haven't shaved in over 10 years. Why? You try shaving your legs, and not seriously cutting them. When I sliced off part of my ankle, that's when I quit.
No-one can tell I don't shave. I'm blessed with really fine hair, so the only place you can 'see' it is on my calves, and very little of them, at that. None of my friends even pay attention to my armpits because they're used to them, and my girlfriends used to play with the hair there. It tickles. >:(
TRIMMING is a must, though. Every girl should trim. I think shaving down there is just nasty. I don't want to look at a pseudo-12 year old.
