I took a sociology of religion course and the professor once brought comics designed for girls going through puberty. It was some sort of sect of Christianity that wasn't accepted by the mainstream (cannot remember the name of it). But basically, the comics said it's okay for girls to masturbate as long as they are thinking of Jesus while doing so, and actually encouraged them to do so. I really wish I could remember the name because I'm sure copies of the comic must be online. Oh, well.
Emma, can you find that for me?
