There are kind of a lot of common misconceptions about the hymen. Someone pointed out already that they can break from non-sexual activities, but you can also potentially have sex without ever breaking it at all, or it can even heal. I'm not sure what the current sex ed curriculums out there are like, but they should probably include "be gentle and maybe you won't tear them a new one." Or perhaps literally just any of what I added to the "they can break from random stuff," for real is that discussed at all? It seems kinda important for that general subject in the spirit of education.
