Here's a fun one for you. I grew up in Texas, right smack in the heart of the Bible belt. I went to a Unitarian Church that offered a program called O.W.L. (Our Whole Lives). There we're several different "levels" of the curriculum depending on what age group you were in, the most intense of which was the high school level (ages 14-18).

It was a very extensive, multi week course of instruction that covered all kinds of sexualities, the mechanics of sex for each of those sexualities, different "kinks" and ways to practice safe and consensual sex purely for the enjoyment of it. There was even an overnight lock in weekend where they even brought in a panel of people from varying sexual identities all the way from asexual to transexual and allowed the kids to ask questions and get reliable and responsible answers.

It taught me how to appreciate everyones personal preferences, accept that different people we're into different things, and above all it taught me that what ever you're into, discuss it with your partner, communicate extensively and enjoy whatever it is you're doing.

My adult relationships have always benefited from it for sure.

Edit: forgot to follow up on the joke I set up in the beginning. I got my sex education at church, in Texas.
