still, it's a clue that what he wants out of the relationship is not an equal partner but a sort of brood mare or something. here in argentina, the kind of guys who would have a problem with former sex work often use the term 'mileage' (kilometraje) when they're talking about why they want to date virgins. they see you as a commodity to be consumed (the explicit analogy is comparing your vagina to a used car) and see your own sexual expression not as an opportunity for your flourishing but as degrading and damaging to you, since you are the good being consumed in the sexual encounter. this is the same conception of human sexual relations that underlies the rhetoric that prostitution is 'selling your body', rather than renting it like any other kind of hazardous physical labor, and that gives the name to the 'purity rings' worn by evangelical high school girls
this implies that, unless he's looking for a no-sex-until-marriage relationship (an honorable but tiny minority of such men), he's looking to exploit you, putting some mileage on your vagina, as he sees it. he's hoping you'll let him degrade your purity with his penis, if you aren't too used up already
of course, different people are different, and not everyone who has these hangups buys into this whole misogynistic ideology. but it's a real thing, and it's something that women have to be cautious of
the practical problems that result, even for non-former-sex-workers, are that guys like that are likely to have problems with the fact that you actually weren't a virgin when you started dating (unless you were, but that's also a tiny minority of all intimate relationships); if, god forbid, you get raped in the future, he might abandon you when you most need him, considering you to be 'damaged goods'; and he probably will feel entitled to cheat on you, since you're the good being consumed, and he's the consumer. in the best possible case, where he wants to be celibate until marriage and honestly monogamous afterwards, you're probably looking at a year or more of celibacy followed by marrying someone you might not have sexual chemistry with
