Virginity?

How old were you when you lost your virginity?
I want to know because even though no one calls me slut or whore, i keep thinking i am one and im really ashamed that my ex boyfriend somehow convinced me to do it when i was 14.. Not the best decision and obviously not my proudest. And telling my future partners kind of ruined how they see me so ive been dumped once bc of this, and ive been used twice before. My current boyfriend accepts me; he makes me feel loved and a lot better about myself.
So, how old were you?
