I was circumsised as a baby so didn't have a say and I have no idea what it is like to have a foreskin. I'm certain that my sensitivity is reduced because the surface of my dick is completely sealed and dry like the rest of my body. I'd be surprised if any kind of virus could penetrate the surface of the skin. On the other hand I have seen guys pull their foreskin back and their dick looks all pink and moist, so I can only assume it must be a lot more sensitive. ML are usually surprised when I tell them they can be a lot more rough with my shaft and it doesn't hurt.

I have been wearing contacts for 20 years and I can touch my eyeballs with my fingers without flinching, similar situation where sensitivity is reduced with friction.

There is just no way having a foreskin can match the hygiene of circumcision, how is this even a debate?
