The hymen begins to naturally disintegrate, and by the mid-teens many girls will only have partial hymens - or none at all.
If you have your period, then your hymen already has torn a bit; this is how the blood is allowed to pass through your body.
Many girls will also break their hymens before sex - rough sports, painful falls that feature your vagina, tampon use, or masturbation by putting things inside yourself will stretch or tear your tampon. You might not even notice this happening.
Depending on your age and experience, your hymen may already be stretched or mostly gonee - even if you're a virgin. This won't affect you in the future.
The uncomfortable, and possibly painful, losing of the virginity is more about the vagina stretching to accomodate something within in than about your cherry 'popping.'
