I have no problem with circumcision if it’s a medical necessity—or if a man chooses that for himself later—but a guy just told me he circumcised his son because it reduces the spread of STDs. Even if that’s true, why would you make choices about his sex life while he’s a newborn?
Circumcision reduces pleasure and sensitivity for men during sexually activity. Originally introduced around 1900 in the United States as a method to reduce childhood masterbation by the folks who invented Kelloggs breakfast cereal.
