I'm the oppostite, the vibes she gave of particulary in the early game were mostly defensive IMO, like she was suffering mild PTSD from all these guys trying to do stuff to her that she wasn't ready for yet.
I never got PTSD vibes from her, more like not wanting to get romantically involved with a guy again due to bad past experiences.
Like when she starts the whole OF thing she is the one guiding and directing MC in the beginning.
She was quite shocked that MC was still a virgin and had no sexual xp whatsoever, she wouldn't have been shocked if she was still a virgin.
Also you dont need to be a virgin to feel that the guy is moving too fast and is forcing for stuff she isn't ready for.
For me the biggest clue is that the game doesn't outright say she is a virgin. Porn games love to point out if a girl/LI is a virgin, as this game does for Cath, Amber and Aliza.
But the best way to solve this would be to just ask WWG the next he pops his head around here.
