I have only shaved my sac before, since one of my gfs liked to fondle my balls/suck/lick on them, and she said it was getting in the way. I have a great deal of hair above my penis, it seems like it's in a V-Shape, but not too much on my sac.
As for shaving anything except the hair on my sac, it is very improbable... I might trim my pubic hair some, but I think I'll stick to brushing/shampooing for a while. I don't shave my happy trail, I just got it last year, I don't plan on getting rid of it. Besides, it's sexy :laughing:
