Uhmm actually, popping your cherry does not mean loosing your virginity. There is a layer of tissue around your vaginal opening called the hymen (look it up for more info). Popping your cherry is slang for tearing this tissue. It is perfectly natural and can happen while horseback riding, sex or fingering, inserting a tampon, intense sports (like tennis), and a lot of other things. It does NOT mean losing your virginity (whoever said that is very misinformed).
