Why do i hurt after using a vibrator?

It sounds like the rectal prolapse may have something to do with this. Im uming you d with the vibrator because you mention tearing your hymen. I was in pain for a few days after my hymen was torn and I bled for these days as well so that sounds normal to me. I think you should use the vibrations on your with no until you get your prolapse fixed and it has healed.
