Bristol speaks to America's teenagers:

She has a healthy baby boy who has just learned to sit up, but Bristol Palin said she's using her fame to tell other teens to do what she didn't do—abstain from sex.

"Regardless of what I did personally, I just think that abstinence is the only ... 100 percent foolproof way to prevent pregnancy," she told "Good Morning America" today, backing away from a previous statement on Fox News that abstinence wasn't realistic, saying it was taken out of context.

Right off the top of my head, Bristol: mutual masturbation, oral sex, anal sex, outercourse, sex toys your partner can insert into you, sex toys you can insert your partner into, erotic role-play that doesn't culminate in vaginal intercourse, GAY SEX—there are lots of "foolproof" ways for teenagers (and adults) to be sexual, to be fully intimate, without risking an unplanned pregnancy. It's possible for a teenager to have fulfilling and low-risk sex, and the intimacy and closeness and connection that comes along with it, without risking the "24-hour job and... huge responsibility" that having a baby entails. Instead of telling teenagers to say no to sex—which will work about as well as telling them to say no to drugs—we should be telling teenagers that, yes, they can wait.

But if they do decide to become sexually active they need to know about birth control—and have access to it—and they need to know that they options. Sex isn't vaginal intercourse or nothing at all. Outercourse, oral, masturbation, and sex toys aren't consolation prizes for teenagers who aren't ready for sex; they're honest-to-God sex acts and that adults enjoy in addition to and sometimes in place of vaginal intercourse.
