We all know abstinence, as a birth control method, is not a good way to avoid pregnancy because the failure rate for abstinence is 100% if a tiny drop of a mistake is made — and many young people today have variable definitions of sex that goes far beyond simple penile penetration of the vagina. You have your sloppy oral sex. You have your crude anal sex. You have your various raw rubbings and rubbery gruntings in the back seats of cars and on den sofas. You don’t know when a drip or a dribble might take a turn for the worse and a baby is the made as the result of a quick-release lust. MTV has a terrific show called — 16 and Pregnant — and it is a magnificent piece of reality television that puts the truth to the lie that unplanned teen pregnancies, and unwed teen moms, are something to be celebrated in the media.
