So, in this novel I've been working on for awhile now, there's some sex. No explicit sex, but it's not vague. It's obvious what's happening. Here's my question - this novel is also kind of YA (protagonist is 18). Is this a no-no? Or does it matter? I mean, it's not erotic kind of sex. I've never read YA with sex, so I'm not sure.
I've been mulling over aging my protagonist by a few years to eliminate this problem all together. The story wouldn't matter that much between 18 and 22. Still, thoughts?
