ThickJohnny: The main ring in the photos is a 00g. I kept all the rings before it and when I freeball in mesh shorts I wear all the rings. Makes for an "interesting" swing. I also wear all the rings when I wear a kilt. There's just enough that they reach the bottom of the kilt, and part of the chain is exposed when I sit down. Otherwise, it's just the one ring.
I think it took me about a year and a half. Only because I thought that a 00g would be disproportionate to my dick. Fortunately for me, my dick is thick enough to balance it out. I have seen long, skinny dicks with bigger rings and they just look out of balance to me.
There's a few guys out there that don't like piercings or are just scared of it. Don't sweat it too much. I have actually put this to the test several times and those that either don't like it, or are scared of it, are bad in bed anyway. So you most likely didn't miss anything there.
Another thing you should get used to are the questions everyone is going to ask you:
1) Did/does that hurt? (nope)
2) Is it going to hurt me? (you gonna love it!)
3) Is it condom safe? (1 ring yes, 2 rings no)
4) Why do you have it? (Why does anyone get a sex toy? Same reason. It's an amplifier)
I know they're just curious, but it does get annoying after a while.
Still, let it heal fully before you start thinking about upsizing. Doing it before you're fully healed will hurt.
