Things are about to get messy.
FYI: Despite these horrifying anecdotes, anal sex can also be very enjoyable if you and your partner(s) are into it. Check out some helpful advice here.
"I met up with a guy from Grindr, and he had the biggest penis I'd ever seen. I had to take his penis out of my ass because it hurt so bad, and he said, 'Damn, you made a mess.' I saw what looked like a gallon of beef stew, and the smell soon followed. He started puking all down my back, and it ran into my hair, eyes, his bed, and the floor. His sister knocked on the door to see what was going on, and he started freaking out. He ran into the bathroom while I, still covered in poop and puke, tried to put on my clothes. It was impossible to leave with any dignity."
"When I was in high school, my boyfriend and I were hooking up in his car, and he suggested we do anal. I agreed, but felt nervous about it because I had no idea what it'd be like. So he put it in and my asshole was not down — I ended up shitting all over him. I immediately started crying while he was wiping his shit-covered dick off with my sock."
