I have shaved my cock, balls and surrounding area for many years with no problems no itchiness no ingrowing hairs. But for the first few months I did have problems with a really bad rash, that itched like hell. I got around it by only shaving once a fortnight for about a month then slowly bought it down to once a week, now I can shave every day, but on average I shave every two days, I like to keep it smooth.
