Hi, i have had a red and sore urethra since i had unprotected anal sex. Ever since i have been checked out numerous times and everything has come back negative. I've been treated for thrush, had thrush cream with steroids in, after this didnt work i was treated for urethritis twice, i then went back to the doctors and have finished a 3 week course erythromcin. Nothing has worked it usually burns when i urinate in the morning and is red and sore after ejaculation
