Don't bother asking. All you will get is simplistic "take it or leave it"(like you can switch your head off now that you know the information) or you'll end up crazy here. My topic was recently closed and I was asked if I'm crazy enough for wanting to "fuck" one girl for the rest of my life. And so what if I do? It is my decision, and only mine. All I see everywhere is majority crushing the morals(in personal, not religious sense) of minority.
If this can be reduced simply to "past is past" tautology, this wouldn't be so frequent occurence in males

At least when it comes to female sex value on market. Look around the internet.
This problem isn't over girl having romantic relationships or wanting a virgin, its whether she was CHEAP. And she won't change her price just because she enters relationship. Ergo, chances are higher she'll cheat if all she needed is some random male taking out his dick. What would stop her? If she doesn't need commitment, what would make her commited? If someone wants to argue otherwise, provide us the strong arguments backed up with meaningful psychology or logic.
Its thin ice if girl had one experience, and we're left with the question was it really no value required, and if she thinks its some kind of accomplishment, but if we're talking repeated behaviour, then its an instinct which cannot be removed, no relationship, no intimacy will change how she is hardwired.
Life serves greater enlightenments, and for some that doesn't mean fucking the number of girls, or adjusting your inner core for others.
And no, I'm not suggesting you to leave her, but to make your own way, but be prepared for attacks on this forum, and in this jungle called society where evolution dictates cannibalism for survival.
