If you don't mind getting your dick out in public, then show 'em and prove 'em wrong. And point and laugh.

And no, it's not weird. I know a couple of guys with a PA done, and I think it's pretty cool. Never had sex with anyone with it done though - not quite sure what that'd be like!

Edit: The guys I know are 20-something and 34 respectively, but I still don't think it's weird for you to have it done at 16. Whatever floats your boat.
