“Would you give a guy that is uncircumcised a hand job the same as a guy that is circumcised?”

The practice is actually so common that many people never come into contact with a partner who has an intact foreskin. That being said, the foreskin can be a HUGE source of pleasure because of the enormous amount of nerve endings found there*.
