One last question - obviously you'd think you'd use the tanning booth naked, yet I would have thought you'd need to wear something across your, uh, private parts as a dose of UV radiation isn't probably too healthy for them I'm guessing. Is this the case?
If it's that bad for your bits, how good can it be for the rest of you?
When I tan in the beds I wear my fave pair of low-waisted Paul Frank briefs. They give you hot tanlines. If you're standing it's not as important to wear underwear as you won't get butt creases (like you do if you're laying down). Your butt might burn if you don't wear something though.
