I guess it depends on how you look at it. :P
He was definitely a monster at one point. And because he fell in love with the Doctor, he is now human.
He was something other than human! He didn't eat food, his body was melting... Lived in a frozen place. I don't think it was the sex per say that changed him but the emotions
heah cuz he had sex with other people before and it ended rather.. badly. for them, at least xd
i like all stories! but i have a question. the uke in the second story, do u think he was never a monster? or he's a monster who turned into a human after a ~meaningful~ sex?
