Is it common to ejaculate when having a bowel movement?

A Discharge with BM?: Often, but not always, a white or clear discharge with a firm bm can be a sign of prostatitis (inflammation of the prostate). If you are not having burning with urination, pain in the groin/low back/testicles/tip of the penis/space between the anus and scrotum, or urinary difficulty or bleeding, then there is generally no need for treatment. Stool softeners may make this less common.
