Living proof that we need better sexual education in this country. The first sex ed class I can remember had pictures of both an uncircumcised, and a circumcised, penis. Not knowing where you are from or your cultural background, it seems more difficult to believe that you didn't know that before now. If you're from the US, most males here are circumcised. The rates are slowly decreasing, but still: "The overall circumcision rate among U.S. males age 14 to 59 is 81 percent." So, I suppose without the religious side explaining what circumcision was, and if you really had that bad of a sex ed teacher, yeah, I guess it's possible.

Many believe it is healthier, cleaner, want the boy to look like dad... Who knows? There are plenty of information on reasons to or not online.
