A Week Ago A Girl Touched My Penis A Little

A week ago a girl touched my penis a little bit for like 5 minutes with her hand. I immediately went home and masturbated and when I was done I had this weird tickeling/tingling sensation in the tip of my penis a little bit inside of the head. I have no sores or redness or pain or discharge or burning and it doesn't hurt to pee. It goes on and off through out the day this past week.
