There's going to be more spelling errors in this than usual because my spell checking isn't working. Hope you can read it anyway.

Anyway, lately I've been having fun with writing a little fantasy story. I'm not really serious with it, but it helps me take my mind off things.
The main character goes on a quest to save a dragon, and along comes his best/only friend. Now, while the main charater does his thing, his friend has his own little side story that ends up having an effect on the main characters quest. Basically the friend starts to realize that he is a sexual being like other humans, and this really fucks things up for the main charater doing the climax. No, he doesn't realize that he is gay and in love with his friend, though there is a strong element of bisexuality to it, but non of those feelings are directed towards the main character.

And then I started wondering: How normal is it in fantasy that sexuality is a major part of the story? I know that characters will often feel lust and have sexual thoughts, but how often does it have an actual effect on the story as a whole? And I'm not thinking of a character being in love with another and then acting differently than they normally would. I mean when the theme "sexuality" in itself means anything. Any good examples?

Just curious because I don't read that much fantasy.
