I do shave my crotch, though not super regularly. The reason is twofold:
1) Pubic hair is crazy itchy. No hair, no itching.
2) The hair gets tugged when your junk moves around, which is both painful and uncomfortable. No hair, no problem.
I shave the area above my junk with an electric razor, though I can't do this with my berries since my razor cuts up the skin if it isn't smooth and flat. The best solution I've found is using a hair removal cream, which works well, but it sometimes misses hairs.
