Im a 35 yr old male. Had unprotected sex with strange girl. Then, had unprotected sex with my girlfriend. Developed pinching pain at tip of penis 3 days later at urethra opening. No discharge or burn during urination. Urine clear. No constipation or swollen glands. Started to feel icy hot burning sensation on penis tip a few days later. My girlfriend developed similar icy hot feeling on her labia which seemed to hurt mostly when wiping with toilet paper. She said she had past yeast infections and this felt completely different. I went to one doctor who took samples of my urine and blood. Tests came back negative for Gonorrhea, Chlamydia, and Herpes. Protein count was high in urine but doctor said it was nothing to be alarmed about. Doctor referred me to urologist. Prior to urologist visit, pain and burning sensation increased so my girlfriend and I went to ER together. Blood, urine, and swab cultures were taken from both of us. We were then treated for STDs (an injection in the arm and 2 cups of medicine). We both felt better immediately after being treated. Since I felt better and both of our ER test results were Negative, I cancelled my urologist appointment. One week later, the burning returned to both of us. The scratchy pinching pain in my penis tip went away but I now had a severe heat sensation in my scrotum and on penis tip. Feels like a continuous hot flash that lasts all day long. There were never any signs of blisters or redness on either of us. 15 days since my initial sexual encounter with strange girl and the heat sensation in my groin was so intense that I returned to the ER. Also had intense heat sensation in face, head, hands, and feet. Doctor visually examined my penis and took urine. Urine was tested in ER; Negative for UTIs. Doctor told me stress could be causing burning which I found hard to believe since my girlfriend had an icy hot feeling on her labia. I had to pass some infection to her. Had urologist examine me 25 days after my unprotected encounter and he said that I had no visible symptoms of STD and since I had so many tests done prior to my visit, he didn
