I have about half an inch of shaft hair.
I tried Nair for men down there and it didn't hurt but it was incredibly itchy, like an itch from hell afterwards. I have never experienced itching that bad in my life. It went away after about 3 hours and the skin felt sort of numb for the rest of the day. The next day though it was perfect, smoothest thing ever, I liked it alot. It grew back really quick though.
I usually just use an electric shaver meant for head hair, with the shortest plastic part. Don't have to worry about cutting myself or anything and it gets a fairly close cut, so I end up with like half a centimeter long hair and it doesn't look unruly or 'boyish'.
Kinda want to try waxing, apparently it lasts for a really long time.
