I watched various movies as a kid where the joke was always the same: “oh noes a man thought the hot chick was a girl but she was really a boy with a dick and he got it up his ass ahrahr”. They were labeled as movies for the whole family. The humor was anti gay and anti trans of course, but I still got the joke. Does this mean the homophobes who wrote those jokes were pushing gay sex onto me as a child? Grow up, sex is a part of life. Kids will know regardless, imho it’d be better to learn about anal sex from something more delicate than a crass 90s movie.
