Question about MacGuffin Chavez’s sexuality

Never read her comics — and why would I? — but is she genetically predisposed to being a lesbian or is it simply a choice in her universe because there’s nothing but women?

Once she journeyed to other universes and discovered the existence of men and penises, is it possible she may prefer them? Or at least be bi?

And what’s with the gay pride pin on her jacket since the concept of “gay” in a universe with only one sex wouldn’t exist.

Or were they already aware of men and moved all their lesbians to that universe like Amazons did to Paradise Island? Or perhaps some are hetero but choose to remain celibate? Or perhaps they massacred all men?

Finally, how do they have kids?
