Good day doc of late im experiencing ed what could be the problem. my urine is yellow and a slight sensetion?

Need to visit doctor: Many over-the-counter pills, creams, and magic potions are advertised to make erections firmer, erections last longer, or a penis bigger, but they do not work (except maybe to give a man extra confidence, which can help a little bit). One can see his primary care doctor or a urologist if one has trouble with erections (due to blood flow problems, low testosterone, psychological stress, etc...).
