Why do we say that we "lose" our virginity?

When I got married, I didn't announce it by saying I "lost" my singleness, when I learn a new skill, I didn't "lose" my lack of ability to perform that skill. Saying you "lost" your virginity is a double negative( since virginity is the lack of something) just a way to shame and guilt people. When we have sex for the first time, we are gaining an experience.
