I was in middle school during the height of the Bush administration's abstinence pushing. A few of the gems I remember:
Our teacher told us all to suck on a peppermint, under the threat that if we accidentally ate the peppermint we would fail the class. Apparently, this was an analogy for the stress we would feel if we allowed ourselves to have sex, "losing control" and biting the peppermint was supposed to represent the stress of maintaining self-control in light of the consequences (because apparently no one's ever used birth control before).
But wait, it gets better! It was actually a two-for-one. After that, she had us all spit them out into a bag, and then passed the bag around saying that we had to try to find our peppermint out of all of the others, reminding us that if we got the wrong one (as we likely would) it would have been in someone else's mouth. She also threatened everyone she brandished the bag at that if they did not take a peppermint, they would fail the class, and that was supposed to represent all of society's pressure to have sex.
This is a routine that continues to this day, and at my high school "peppermint" has even become a pet name for dating partners who have become sexually involved. You have to admit "peppermint" does sound a little cute, if sappy.
Oh, there was also this gem about how latex powder and lubricant from condoms could get into your urethra and cause permanent urinary tract damage and sterility/infertility and permanent and complete sexual dysfunction.
They trotted out the same tired nonsense about how birth control pills will give you acne and stunt your growth and make you obese and cause cancer, or how the morning after pill would allegedly sometimes make a woman's entire uterus, womb, and ovaries, literally fall out of a woman's vagina, the same story was alternately given about abortion (pro or anti choice, let's please at least stick to facts, thanks). Of course, the course material neglected to mention that prolapse of the uterus actually DOES occasionally happen....during CHILDBIRTH.
They told us that homosexuality directly leads to depression and mental disability, and had a baloney scientific "study" indicating that homosexuality is something people usually just do to get drugs or because they feel rebellious, complete with a link to none other than heritage.org and openly advocating for any students reading it who "might be considering homosexuality" (exact words) to seek reparative therapy and to "think about the costs to your friends and family".
A note about the last point. They'd cooked up this pop-psychology thing called "the bio-psycho-social" perspective, including a neat little triangle diagram. Whenever they wanted to say something was good or bad, they would use the "triangle chart" with all of the negatives for each category, ie, biological, social, and psychological.
So, they would bullshit that homosexuality was bad biologically because it "causes STDs", psychologically because "it results from depression and a lack of self-esteem", and (most offensively), being gay apparently hurts you socially for no other reason that that it would make people not like you. That was it. Their argument against homosexuality was homophobia itself.
Whenever they wanted to drive something home, they would finish it off with the social perspective. If you're "thinking about trying homosexuality", then "think about how your family will feel". If you're thinking about sexual intimacy, then you need to think about how it will hurt the feelz of your family and Jesus or something, I guess. And you need to get married (ideally when you're still in your most fertile years, because your highest calling as a human being is to be breeding stock) because it's popular and you'll be hurting all of your friends and family if you don't, and they'll also laugh at you and you'll probably commit suicide by 30 if you're still single by then.
Oh, then there was telling us that it was illegal for minors to get condoms and birth control. Yea, THAT'S going to reduce teen pregnancy. Fuck, you'd think that if they cared as much about reducing teen pregnancy as they did about pushing you into getting married, they'd be advocating tubal ligatures and for condoms to be surgically grafted onto every boy's penis the instant he hit puberty.
Finally, there was an entire chapter on masturbation. Include a foreword by Bill O'Reilly! Apparently, very few people masturbate and those that do are using it as a crutch to deal with various personality failings, the tired rhetoric about how jerking off can cause brain damage and permanent sexual dysfunction, infertility, acne, etc. Masturbation, they said, was the first step towards "unsafe" sex, including homosexuality, and that the teenagers who were masturbating were the ones who were "almost certain" to get an STD or knock someone up because it speaks to our lack of self-control.
Now, I "discovered myself" when I was 11, and had been continuing to "discover myself" pretty regularly (ie daily) between then and through most of high school, so now this book has me thinking I'm a sex addict (I didn't learn the actual statistics until much later) and one of a select few number of perverts who are almost certainly going to have to drop out at 16 to raise a baby and probably die of AIDS that I caught in a gay bar.
I look back on it and laugh now, but it actually really did leave me with a lot of anxieties about dating. I actually did go out of that class thinking that if I went beyond hand-holding and Christian side-hugging (our course actually said that we should only "side hug" though it left out the Christian bit) I would inevitably lose control and end up getting some girl pregnant. I was 13 and seriously worrying about what I'd do if I had a kid. I wasn't even in high school and I was judging girls based on whether or not they would make good mothers if it came to that, which in my mind was a possibility that had been made all but certain: if I dated, I would almost certainly have sex (remember, I was a masturbation addict with no self-control, allegedly), and because protection was illegal for teenagers, that would inevitably result in a pregnancy.
So yea. There's my shitty sex ed story.
