A couple of weeks ago I had unprotected oral sex and the next week I had a funny feeling when I urinated. It did not hurt, burn, no discharge, and no blood. I went to the doc and was tested for gonnerhea and chalmadia and the test were negative. I recently woke up with 3 red dots in my mouth on my upper lip, that later turned into a something like a 3 little sores; that i only felt if I hit it while eating or if it something hot touches it. But I still would not consider it be painful. The little sores are going away now; I've only had it for four days. Should I be worried about any other stds?
