To be honest, circumcised or not, you still shouldn't be having unprotected sex if you don't have the intention of procreating, and Condoms are way not only proven to prevent STDs, they also don't have the long term effects of circumcision.

Wait, 300 feet? How in the hell can you fit 300 feet of blood vessels into something that tiny?

I don't believe in circumcision. The whole thing about you being less likely to catch STDs only reduces the chance by a miniscule amount, but really, no one does that to babies for that reason.
Doesn't it seem odd that, if you are created in the image of God, God would have a foreskin? But then why would God give you a part of your body and then command you to chop it off?
