This is a very embarresing topic for me. Recently I was arroused and had the idea of seeing how far I could push the pipe form the shower up my anus. I got it a good 10 inches in when I felt a pop, I assumed this was the passing of a sphincter, but it was extremely uncomfortable so I stopped. 15 minutes later I now have discomfort in my lower left abdomen. Could I have damaged my colon, or will this pain go away?
Inserting foreign bodies into the rectum for sexual stimulation puts one at risk for anal injury and even rectal perforation.
Experiencing left lower abdominal pain or tenderness with abdominal distention, anal bleeding may indicate a rectal perforation.
See your physician or abdominal surgeon as soon as possible!
