I had a sexual encounter with a sex worked I think I was exposed to an STD. I went to the doctor a few days later complaining of a sensitive penis "tip"/ pressure and irritation after I urinated. He prescribed some antibiotics and said it was most likely just anxiety. 2 weeks later have less of a sensation at the tip of my penis, but my groins are swollen, and my lower abdomen has be aching as well as my lower back/ kidney area, the tip of my penis is only sensitive when i rub it purposefully against my shorts. The glands and aching are making me feel like an old man. also i feel like my legs are very stiff and need to be stretched a lot. More details, never and confirmed discharge, although it felt like it, and we wore a condom but i wasn't that erect, Why am I in such pain? Damn.
