I'm starting a new story and it's about a boy who lives a short time in the future in a closed community; seemingly the typical future as dystopia (never fear though, I have plenty of twists) and I'd like him to be young; I'd love 11. BUT, in the story he is going to have oral sex with a girl a little older (maybe 15ish). As a former middle school teacher I know that kids this young are engaging in these behaviors, but I don't want to shock my reader so much that they are pulled up out of the story. Obviously, this is adult fiction, or YA for mature readers, but I'd like a second/third/etc. opinion: is 11 too young? For literature, of course, not for real life.
