I'm from the other thread, the one where I defected into my cubicle trashcan and got fired.
I. LOVE. FISTING! But >>2875763 is right, you have to be super careful and its a lot of time and effort. Luckily I already screwed up my anus enough to not care, and the best thing in the world is hands. Hands down. Just make sure they're lubed and shaven or covered with a latex glove.
Reason being, is your asshole is porous. I met this one girl at a bar, brought her home, and when she was sucking my cock she noticed my asshole. It was gaped but frumpy looking. So curiousness took over her. One finger, two, three, fist. The first draw in, she was too rough, and felt like she was pushing for my large small intestines. While it felt good, and I came all over his burnt orange hair, somewhere in the process her fake nail came off and didn't bother to tell me about it.
I got a really nasty infection because of it, some sort of anal abcess that resulted in my medical coverage being pushed to the max. The next time, my boyfriend (ex now) had bear arms and hands. He had rubbed the scar tissue raw, and some of his hand hair got in there. Long story short, I got a nasty internal anal zit. Every time I shat, it was like popping a large nose pimple. Cream and blood would come spurt out followed by shit.
