A cherry is slang term for when your hymen breaks. Your hymen is a layer of skin located inside of the vagina that breaks when you have sex, use a tampon, among other things. Your hymen can break from just riding a bike. It tends to bleed, but it depends on the person on how much it bleeds. A lot of girls think that just because their 'cherry has popped' they have lost their virginity, but this is not true. You don't lose your virginity until you have actual sex.
