ELI5: Why do so many Americans circumcise their children?
gpt
Circumcision was introduced to the American masses in the 19th century as a way to curb STDs and masturbation. The practice caught on, and now probably the most prevalent reason that we continue circumcising our boys is societal, i.e. everyone's doing it. If you're uncircumcised and someone finds out (friends, potential lovers, etc.), then you're probably going to be shamed for it (there's even an episode of Sex and the City where one of them shames a partner into getting circumcised).
