It's obvious she's attracted to women and not men, she gets turned on just by looking at herself.
Also, she has all of her past life experiences and memories. Memories are just neurons, millions of webbed organic shit in our brain.
And guess what? The person that's in this body had literally overwritten the girl' brain, the guy is in control.
Just because he's now in a females body, doesn't mean she's going to be attracted to the opposite sex.
Remember when I said memories and experiences are just organic webs of neurons? That means they're physical. We're all basically organically hard wired. Sexual attraction/preferences is therfore also hardwired.
And in the guy's previous life, he was straight.
His brain chemical makeup merged with and is dominant in comparison to the woman's, he has all of his memories and experiences, and all of her memories and experiences, but it's the guy that's dominant and in control.
Yes, his body is that of a womans, he doesn't have male genitals anymore, but he was a straight man, therefore he's a lesbian, because he's not attracted to men.
Having a penis or a vagina doesn't dictate you're 100% going to be attracted to the opposite sex. That's just not how it works.
