When I was a teenager in the evangelical Christian world of the late 90s, it was pounded into my head that having sex outside of marriage was the worstest, most terriblest, sinnliest sin I could commit outside of murder.
I was given lessons at church camp about how once I had sex, I’d be a “chewed up piece of gum.” In another youth group lesson, we were all given a piece of tape. Some of us would stick ours on the back of other people’s hands, and some wouldn’t. The more people we stuck, the less sticky the tape got. Only the “pure” tape people stuck together in the end -- the lesson being that if you had sex before marriage, surely your union would fall apart, as you had used up all your “glue” on other people.
