What books, documentary films, or youtube channels can you recommend to learn about healthy sexuality?

I was raised in purity culture to the extent that I only found out how people had sex when I was 18 when I stumbled across it on a fanfiction. I would like to learn more about what is healthy sexuality and how to understand your feelings and how to communicate boundaries. Both straight and queer sources are welcome, as I have no idea which one I am! Thank you.
