I don't assume everyone above 18 has gotten laid, because to be less serious - walk into any engineering lecture and... well, yeah.
I'm just saying that if you are going to limit your choice of husband to those who are virgins, you are probably cutting out a very significant portion of men who will love you very much and who you will be attracted to, and you will not consider them at all, for arguably - little reason.
I know virginity means a lot to you but if you met the right guy who... say, made an error in judgement one night many years ago... then it may be a bit harsh to reject him outright.
Or, of course, I also see that perhaps you are optimistic that you'll find someone similar, or better - who hasn't "made that mistake". Correct?
