Being a virgin would explain her lack of sexuality, and it's possible if she's a lesbian, but my guess would be similar to what
juliopopens suggested. She probably lost her virginity at a very early age, and quite possibly in a non-consensual way, which basically destroyed her interest in sex. This would explain her awkward interactions with + lack of interest in men, and it would also explain the overwhelming cringe when she's with women.
The only time she ever seems relatively comfortable is when she's masturbating, which makes perfect sense if the above is true.
But even if all of that is true, it's still no excuse to be a scamming cunt, which is exactly what she is. Yeah, she's got an agency running her OF, and they're technically the ones doing the scamming, but she's complicit in all of it, and that's just as bad.
