About two weeks ago, while drunk, I was shaking off my penis after urinating, and basically "smacked" my penis fairly hard against the top of my jeans fly opening. It was somewhat painful, and since then I have experienced a dull soreness near the tip of my penis. It hurts when pressure is applied to the top of the shaft / lower part of the tip. There is no discoloration or visible bruising. It does not hurt when no pressure is applied, it is only when I apply direct pressure that I notice the mild discomfort; i.e.: drying off with a towel, putting on underwear, pressing against a surface, etc. Again, no sharp pain, it feels like a dull bruising. However, it has remained for almost two weeks, which seems unusual. The pain felt like it was subsiding, but after engaging in sex on Saturday, the pain has become more pronounced Sunday and this morning.
Additionally, I have had a persistent cough for about one month. It comes in fits. I will be fine for several hours, then all the sudden I am violently coughing for twenty minutes.
Might these be related? Any STD possibilities? I am married, have had nothing but normal spousal sex.
