I was watching some porn bloopers

And more than half of them involved a girl shitting an an inappropriate time. Like one clip had girls peeing on another girl, and this girl was trying to make herself pee and she dropped a chocolate raisin, she even tried to scoop it up behind her. And in another clip, this girl was masturbating in an orgy room, and another girl wanted to eat her out, so she pulled her panties to the side and she had crapped herself a little.

Are these girls just retarded or do women have a legit problem with not shitting themselves randomly?

they are so fucked out that they have nerve damage

If you think about what porn means, the answer should be fairly evident. If you're stretching the anus, you're going to have problems. Incontinence problems.
