How can you break your hymen without having sex?

Fingers: Fingers, devices, non sexual blunt trauma possibly.

Lots of things: The hymen is basically a thin door with a small opening for menstrual blood.Anything that is pushed through the hymen can break it. Sex toy, cucumber, fingers, etc. Simple exercises or yoga will not.

Why?: There is no good reason for doing that, unless the hymen is so closed that menstrual flow cannot freely leave the uterus and vagina, or a tampon cannot easily go in or out of the vagina. Otherwise, the hymen should be left alone.
