Sex was avoided as a topic, but we were taught that premarital sex is a sin. I was also teased as a kid about having crushes on girls (I'm male), despite my adament (and truthful) denials, and othertimes they'd joke that I'd change my mind once I was older. I won that though - turns out I was gay and never did change my mind.
As for LGBT issues, it was so taboo / not talked about that I didn't even connect my confusing feelings for male classmates with me being gay until I was 18. I thought everyone felt like that and was frustrated when they wouldn't reciprocate those emotions back.
