I think shaving sucks. Never tried waxing, but shaving itches like a bitch later, and once in a while you get ingrown hairs or some other shit like cuts or red bumps. This may be acceptable with heroin addicts who are used to the itch, and do not mind their girl thinking you have VD. For the rest of us, an electric trimmer is the way to go.
Have not tried trimming my ass though. Cant say I want it shaved either ;/
Btw, I had doubts at first when they opened the guy's stuff forum. Boy how wrong was I. This is essential, keep it up fellas.
