Virginity matters to a lot of people, and insofar as it is an indication of the person’s morality, it is significant. I certainly did not want to marry a man who was sexually experienced.
But someone who has slept around has no right to demand a virgin.
People who are not virgins are not necessarily immoral.
Having a preference for something is different from prioritizing or fetishizing it. Making the search for the partner all about finding a virgin is idiotic. Devaluing a human being based on whether or not s/he is a virgin is disgusting and immoral.
