Back to your original questions:
Yes I shave my bush, shaft and balls.
If it's your first time shaving, you should first trim the hair down as short as possible - with clippers, beard trimmer or scissors. (Careful using something like a beard trimmer on your balls. Use a guide that leaves at least 1/4 inch and hold the ball skin as taut as possible or you can cut yourself)
Then get in a hot shower, let the hair soften up. use shaving cream and a fresh razor blade. Pull the loose skin (like shaft and sack) as taut as possible while shaving. Rinse the razor frequently to clean out the hair and avoid irritation. First couple of times, I'd recommend shaving with the grain. It won't be perfectly smooth but less risk of ingrown hairs. As your skin gets used to being shaved after a few times, you can go against the grain for the smoothest possible shave.
After you shave, rinse the whole area with very cold water to close the pores. Try to pat dry rather than rubbing, and when dry, powder - lots of it. I recommend Johnson's Baby Powder with Aloe and Vitamin E.
The next couple of showers, gently exfoliate to avoid ingrown hairs. And again, when you get dressed - POWDER.
Enjoy the experiment. If you like it, maintain it. If you don't, hair grows back.
