I am 20 years old and I have been working out my PC muscles for about 6-7 years now. But, whenever I do the exercises, or when they contract/expand while I'm having an orgasm, I always feel the need to do bowel movements (excreting feces, specifically) about 5 minutes afterwards. But, if I completely relax while I'm having an orgasm, this never happens, so I am assuming this has something to do with a connection between my PC muscles and somewhere in my rectum or something. I am also pretty sure I am doing the exercises correctly because my legs/stomach area is not stressed when I do them. I have never heard of this before on anywhere I've read, and I'm a bit embarassed to ask a doctor in person. Do you have any idea why this could be?
