Haven't you heard? Only married people (man and woman) can make babies! Sex is for procreation ONLY, and only within the confines of marriage. To imply otherwise condones all sorts of immoral and promiscuous behavior! You wouldn't want people to get ideas. :P

Gee whilikers, maybe I should get a health book. I'll need to know what to look forward to on my wedding night. Bwwaaahh-hhaaa-haaa!!!
