Re: shaving genital hair
Ingrown hairs (from not shaving regularly) and an occasional nick from the blade are the only health risks I'm aware of. I'll bet you shave your legs and arm pits, and most guys shave their faces without health problems.
I like a clean-shaven woman, but it's got to be a "clean" shave. A 3-day-old beard is rough and not pleasant for anyone. If you're going to shave, plan on shaving as a daily routine. A clean shave is nice for oral play -- nice for the giver and, I'm told, nice for the receiver as well.
An alternative is a light trim with a scissors to keep it groomed. That's what my wife usually does, and I like that too. Clean shaven would be nicer, but it requires a lot of time to keep it that way.
The only way my wife removes it is when I shave her. I know some use chemicals or wax, but I don't know about those methods.
