Personally when I was powerlifting I would shave cause the wraps just tore the crap out of my hair. I used a DE or schick hydro. I would actually just use warm water and stand on a towel in front of the mirror, wet the snot out of the body part, lather, shave, then shower afterward. Never had a problem there, I would just rinse off and hit the NO NO bits w/ soap, b/c shaving soap and cream, are well...soap, so you would kinda be doing a traditional japanese bath of sorts I guess.
