Middle School (Mississippi): Basically all lies: having sex with a condom will give you AIDS, abortions are evil and most women who get them die of cancer or suicide. Even 6th grade me knew that shit was fucking wrong, but I was already on thin ice in that school for fucking up the curve, thank Homosexual Jesus that I was only there half a year.
Junior High (New Jersey): Skip ahead to 9th grade. Sex-Ed was taught by a terrified gym teacher who was just adorable. This was pretty comprehensive, lots of biology and factual information. It was the early 90s so a big part of it was teaching how to avoid getting HIV, teaching both abstinence and condoms. Some mention of same-sex relationships, but when asked about the risk of HIV transmission from lesbian sex he blanched and said he didn't know. No real fault here given the time period. They also taught various forms of birth control and other STIs. There was an undercurrent of promoting abstinence but also some pragmatic realism. In retrospect it could have been better, but compared to most of the country it was very good.
