Okay, I have a question. If she becomes a he - and being gay is not a choice, but something you’re born as - then won’t her girlfriend no longer be attracted to her because she will be a he?
Don’t think about it too much, your head will explode.
Here’s one for you.. a female model decides she is a lesbian.. then decides she’s really a man trapped in a womans body.. so she has the skin off her butt rolled into a sausage and has it attached to her groin. Then after a few years of living “as a man” now decides she’s actually now a gay man. So, when she’s a woman she’s into women... so she goes and gets a fauxllus because she must be a man in a womans body.. then once she gets the fauxllus, she decides she’s actually not into women at all but men, and is a gay man.
No, I’m not making this up.
Homosexuality is mental illness folks, nothing more.
