What do you mean by "break" anyway? I always assumed that the word "break" is used (however incorrectly) to mean that hymens tear and wear away from sex and tampon usage. Hymens can definitely tear and bleed from either. Also, a woman who has given birth vaginally will usually lose all traces of her hymen. A torn hymen is the same as a broken hymen - I think this is just a matter of definition.
