A few thoughts on mine...

It didn't hurt much to be honest, just a quick burning sensation and was all good to go within weeks. Nips were way worse!

Nice sensation for both parties and feel nice when masturbating.

It actually improved my aim when pissing, I used to fire towards the right side but now it's straight down!

If you are getting crust on it you seriously need to take a look at your general hygiene.
