I too was brought up Catholic and went to Catholic schools from kindergarten through high school. About the only things we were taught about sex was that it was a dirty act and a necessary evil. Masturbation was a sin as serious as murder and would send you straight to hell. The only advice on sex I heard was from a priest during my senior year. This involved when and how frequently a couple was to have sex, and the act should never be performed merely for pleasure. Birth control was forbidden, regardless of how many children a couple had. I found it odd that we should be getting advice from a man who was never married, didn't support a family, and never held down a legitimate job in his entire life. My parents told me nothing at all about sex.
