Anal cracking is When you use too many dildos causing your asshole to grow a bone and every every step you take, your anal bone cracks. Therefore , don't use too many dildos. Anal beads don't count. The cure: Stop being a slut. Talk to your doctor to get a butt replacement.
Anal fracturing is when you have someone pour about 1 cup of liquid nitrogen into and onto your anus, then having a man with large genitals come and shatter the frozen parts of your ass.
Aw dude, look at that chick over there. I would love to give her a goodanal fracturing.
