Because I had a serious question about if there have ever been cases of a medical anomaly where a vagina and rectum have switched places, and I'm pretty sure it was in that thread.
i was actually just reading about imperorate hymens and then came across that.
BY THE WAY:
Imperforate hymen - lack of vaginal opening due to a completely solid hymen. So when a girl has this, her first period will never come. Instead, it all just gets back up inside of her and her hymen bulges out like a water balloon, except filled with blood.
