Ok, so here's the story. About 7 months ago I had unprotected sex with a girl who's been around the block. It was a bad decision I know, I've beat myself up about it enough. Anyways, ever since then I've seemed to notice when I urinate it just feels kinda different. At first I wasn't sure if it was my mind playing tricks with me because of the anxiety, or if I had an STD. It wouldn't necessarily sting, but whenever I flex my penis I feel discomfort near the tip, or whenever I begin my urination the tip feels irritated. Also, after I've urinated the inside of my penis feels irritated for about an hour. I kind of get this whole...shaky/washed out feeling. The only time my penis doesn't get the irritation feeling is when I'm doing sport practices. Like when I loosen up and stretch and start running around I'm just fine. Anyways, so I was real worried so I went and got tested for Chlamydia and gonorrhea. Both test came back negative so I felt pretty good about that. That was about 2 months ago, and I still get the same irritation. I really want to know what's goin on, it's causing me to get performance anxiety to the max and I hate that. Overall it's just a stressful situation. If anyone can tell me what they think is going on I'd really appreciate it.

Thanks
