Homosexuality

Homosexual characters are romantically and/or sexually attracted to the same gender. If you want to be less formal, you can call them "gay" or "lesbian" or, y'know, just use their names.

There's a severe shortage of good homosexual characters in fiction; so people who write fanfiction often write a straight character as gay. This can be done well or done badly; and while it's technically an AU, it's usually just called slash, which refers specifically to same-sex romance and is usually the reason someone would write a canonically straight character as gay or bi.

Lots of characters don't have a mentioned sexual orientation; so, just as long as they're kept IC, the writer can take his pick.
