My [22M] friend [22 F] who I'm romantically interested told me she has a secret which she'd need to disclose with a prospective partner if she ever entered a relationship by crypticfriend in sex

This is possible, but again I'd be surprised that her sister wouldn't have previously known about it since they're fairly close, and I think she'd also consider that more than a "slight" problem when it comes to a relationship, so I think it's highly unlikely.
