question: Hello, For some time now when I use the bathroom I ve noticed a yellow to brownish slime come out of my anus, almost like snot. Sometimes I get on the toilet just to see if any will come out. It has a distinctive smell almost like urine or metal-like. Should I be concerned? I do have anal sex from to time. Is this some type of infection? I ve been a little constipated but nothing to major. Please help
