Is life perfect? no. Can you enjoy things in life anyway? yes. All right, so we've established that not everything is gonna be a Disney novel, but we can find our spot anyway. What this means is you don't need a virgin.
Next there's the question of where you get your sense of self-worth. Guys who get it from things they can't control but which can control the validation they get from them, like another person, are in a blue pill state of mind. That's why posing with a celebrity on your instagram photo should not make you feel better, and why being uncomfortable having a girlfriend who has taken more cvm than your buddy's wife - while a perfectly valid feeling - in actuality means you don't feel complete without validating yourself through her. Is it gonna be easy to get to that mental point? no, but you aim there to get as close as you can. Living without need for validation is what freedom is.
If you don't need to be validated through her, how much does it really matter if she's svcked 0, 3 or 15 d!cks before you in of itself? try to find an answer that doesn't revolve to what someone thinks of you.
What matters to me (theoretically as I've never bothered with a ltr) is her congruence, honesty, self-respect, and that she's faithful while in a relationship. What congruence and honesty mean is for example, I have more respect for a girl who likes men and likes having sex, understands men may not want her for that reason and is open about that and herself, than an ex-party girl who now pretends to be another kind of woman (for as long as she thinks she has to). Self-respect means if she doesn't respect herself, neither can I. If I find out she's had 3 partners but she ate their @sses and they were disgusting lowlifes, I would rather be with a girl who's had 100 partners.
In summary what you should ask yourself is, does she respect or look up to you? does she respect herself? does she like to please you? do you enjoy being with her? does she turn you on? if yes, you next need to find out why. Is it because that's who she is, or who she pretends to be? if it's who she really is, then you have found "good enough", which is what reality runs on.
TL;DR: the specific number itself is irrelevant.
