Advice for Dragon Empires Villain

[Kazarath]

I've started a campaign set in the Dragon Empires, and the first session was last monday. It was a rousing success, and one of my players at first thought I was doing a published adventure. But I've run into a little snag, and I'd like some advice. If you think your one of my players DON"T READ THIS!!!!!

Spoiler:

Right now I'm working on the villain. I've decided to make the MAIN BBEG the lovechild of the Goddesses Daikitsu, the patron of the kitsune and craftsmen, and Nalinivati, patron of the Naga and goddess of fertility, whose romance was hinted at in the Gazetteer. Don't ask me the mechanics of how two female gods gave birth to a child. Anywho, I wanted this demigod to have been born with a horribly warped mind, due to the interplay of the two wildly different cosmic foci. Completely insane, the child had to be imprisoned due to it's bloodthirstiness and cannibalistic tendencies. The plot is going to revolve around some insane man/woman attempting to free this monster blah blah blah.......

My problem is deciding on the gender of this demigod. I would like to make it female, due to the fact that both its parents are female. But out of the last three campaigns I've run, two of them the significant villain was a woman, and I don't want my players to see a pattern and start thinking I'm sexist (which I am not BTW). The fact that our entire group is male might 'soften the blow', so to speak, but its still something I worry about.

Advice?

Asexual? Reproduces by partially eating and regurgitating victims into its canniblalistic "children" with demonic strength. Children/followers can always refer to it as "Parent" or "Great Being" or "The Devourer" and never with any informal pronouns like it/he/she.
