Inching in Penis and urge to urinate frequently

Patient: I had an unprotected sex with a girl friend. After the sex I started constant itching on the top of my penis and urge to pee regularly which was the never the case before. The inching is pretty much constant in penis now (towards the releasing point) and I got about 10-12 times to urinate which earlier used to 2-3 times a day

Symptoms: Inching in penis, urging to urinate frequently
