Do you all have virginity as a preference, if yeah, why?

Well this is obviously more targeted towards older teens but whatever, I saw a bunch of people I know (17-21 in ages) discuss about the thing and how serious they were T-T, they were like "koi randi nahi chahiye broo"

So now I am curious, what's the point of having it and why do some people deem it so nessecary as a preference.

Note; I don't hate anyone with preferences, it's your life and your choice who to form relationships with, idgaf.
