E up the ass ain't a good idea... my ex insisted that would be the way to roll, and I obliged her by doing the duty. In her brilliance, she decided that by crumbling it up first would be the way to do it. I guess she thought that it would be a harder roll that way.
So we crumbled it up, mixed it with some lube, and in it went. Before I got to the first knuckle she was howling in pain. Apparently, those little e pieces are pretty damn sharp, lube or not. I thought she was being a wuss until she had a bit of blood coming out of there. Fun for the whole family!
