Translayer

Connor: So, Vampire Slayers. I was told about them. How come you're always girls?
Faith: I don't know. Better at it, I guess.



So, vampire slayers. Always girls. Anyone - those pseudo-canony things or in fic - ever explored the trans angle? I'm asking seriously, not talking crack fic.

Is it a woman thing? If so, can a slayer be a girl with a male body? What would the watchers do? Or is it a body, DNA, chromosome thing, in which case, what happens if a slayer is on testosterone and on his way towards chest surgery? And what happens with intersex people, how does that work re slayerhood? There's been tons of slayers through the ages, no way did this never come up, unless the "only girls" thing is extremely severe and somehow picky. In which case, I still want to know how it works.
