Is my cherry popped? I stuck things down there but didn't bleed

Having your cherry popped is another term for loosing your virginity, which happens the first time you have sexual intercourse. So if you have only masturbated then no.
Some girls can break their hymen playing sport or in the course of normal daily activities or may have been born without one, so having an intact hymen or the lack there of, should not be used to determine the girl virgin status.
Enjoy masturbating.
