It's hard to say. She never says she had experience, but she was living in a "I am dating <MC>" mode until two months ago. Spurred on in part because her friend was teasing her for never dating. I lean towards "no real experience" until given better evidence.
Something happened in Bailey's last relationship which is why Rainy is worried about her. I doubt she's a virgin.
Did you miss her "Never have I ever" game? She said she had never been with a man.
Zoe's done plenty enough.
Zoe "Is sex always like that?"
Zoe "I mean... for you?"
Honestly, that felt like her catching herself half-admitting never having had "real" sex, but that's my take
Jasmine and Damien haven't done anything, nothing to say she hasn't slept with anyone before.
Just given the current pattern, and the fact they've been together for four years having done nothing, it seems unlikely.
This isn't a High school romance game, most of the girls have some experience.
Indeed it isn't, but there's already a large degree of "unrealistic" qualities in this game to base your position on "this is college". This isn't me projecting my desires onto the game, this is me looking at what's in it and making my analysis.
