I don't really think it's possible to have an opinion on what God would do in a situation like that, he is a mystery to us and you just have to hope it happens but also accept that it might not, and consider that their might be upsides to that, try not to see it as a bad thing if your future partner is not a virgin.
But at age 21 I'd say your chances are fairly good, mine at 26 are probably not so good but while it would be special if my partner was also I wouldn't be bothered if she wasn't, her past would not concern me much as I'd be thinking about our future.
