Sometimes after I pee, I feel a pain that makes me feel as if I haven't completely emptied my bladder. I'm not sure what causes this, and it only happens about once or twice every other month. I'm not sexually active, so it's not an STD. Maybe this is just normal? Any help is appreciated.
I should also add I have Ulcerative Colitis, and I don't masturbate either. Maybe it has something to do with that?
