Shaving....*ahem* (sorta NSFW)

[Scruff7]

Maybe you have crabs. that would itch.

if you shave them, prepare for almighty itchiness as soon as the little hairs start to grow back.

and the greasiness... i think that's probably normal, just wash em regularly, i sometimes use some anti-persperant on them (not a lot), can keep the moistness out.

other than that, you just have to learn to live with your little friends.

P.S. its normal to itch them, every guy does it. 'Adjusting' them is just a little piece of being a man, you just get better at doing it subtly. the old 'pocket fondle' is my favourite.
