After I discovered that I was a bottom and started experimenting with a dildo in my asshole, my sphincter muscle was sort of confused. Every time I got the dildo up inside, I felt as though I needed to have a bowel movement. Which, as I discovered, was not the case.
In fact, it took a while before the needing to poop feelings went away completely. I guess the sphincter is not used to incoming traffic and thinks, oh it must be time to poop!
At first, I thought it was a little strange using my rectum as a sexual organ but I think it makes sense. The urethra in a male penis does double duty, being used to urinate as well as to ejaculate. So why shouldn't the rectum do double duty as well? It almost seems planned that way!
