Okay I'm 17 I haven't had but two sex partners one was several months ago. The other one is my current girlfriend and before her sex wasn't really a thing. But last night I noticed a itchy feeling on the top of my penis. I looked it up and also looked to see what the deal was and that was when I saw the seepage by then I had an idea of what it could be (urethritis) but I had my doubts because I've only really had sex with her. But more information about me and her. We have been dating for something like 3-4 months sex only more recently for the last month. She said she had been tested and doesn't have any std so could it just be an infection? My penis isn't swollen and doesn't hurt to pee. It did hurt though a few days prior to this. I'm really worried about this and I don't know when I should have a doctor look at it. Also the we have been more sexually active this past week having sex twice a day sometimes and atleast once a day.
