why does my urethra itch, but only when there is pin pointed pressure? the only time urination burn is after i have "scratched" my urethra. i wouldn't say scratch, more like a gentle rub as you would do for a bug bite. when i rub my urethra, it occasionally makes me have to urinate, but rarely in normal amounts, usually smaller amounts. the itching only occurs toward the base of my penis. moving further to the end of the urethra (away from my body), the itch becomes less and less noticeable. i did have unprotected sex with my girlfriend, however, she was a virgin, so i am assuming that an STD is out of the question. what could be causing this?
