I recently had sex with a hooker and we used a condom. 2 days later I felt a constant pressure in my penis especially after I pee or enjaculate. There are no physical signs of any kind showing on my penis. The pressure is sometimes slight, but always there. i have had a history of uti, but the doc did a quick check in the lab and came out neg for that. I took an std test urine and blood and am awaiting results. I am stressing out big time, anyone know wht this can be??
