I had to read up on this subject when I was deciding what to do with my baby lemur's johnson. Here's the deal, as I understand it: The foreskin protects the head of the penis, which means it remains both more tender and more sensitive. A cut johnson has no such protection, so it toughens up at the tip. Thus an uncut johnson is more prone to suffer micro-cuts during vigorous sex. I can only imagine the damage done by dry sex to an uncircumcised johnson.

I didn't bring up the freaky-deaky practice of dry sex just for the shock value; all of the studies that showed circumcision lowers HIV transmission were conducted in areas where the dry sex is common. I would be very interested to see if the same results hold true in places where men don't jump for joy at subjecting their tenderest appendage to a sandpaper treatment.
