k, I'm dating myself, but when I was in high school, the big scare was herpes, because it wasn't curable. There were even herpes dating services (phone in those days, 'cause no web) for people who had herpes...

Other than that, I knew a lot of people who went without protection. Of course, I don't think I even *knew* a gay person in high school... so I'm speaking of hetero couples.

In fact, at my hippie high school, the teachers gave "awards" to students at graduation, which were humorous things, and one very visible couple received the "Couple most likely to concieve" award. I think I got the "How to succeed in business without asking anyone" award or something... long story...
