A flat red tiny dot appeared on the right side of my penis right below the head by the ring (if you know what I'm talking about).. It appeared in the middle of January of this year and disappeared in 2 weeks. On the second week it started looking like a blister or sore I guess. So I started putting fungus cream on it. I went to the doctor but he couldn't Identify it cause it was gone by then. The doctor told me don't worry about it since it went away. I took all the std test and the results came back negative. Unfortunately it came back last week and the odd thing about it is that it appeared on the same spot where it was the last time. I'm sort of not worry about it because I took all the test and the results came back normal but like I said its weird that it appeared in the same spot. So now that's making me worry. I need help. I been with the same girl for over 8 months.. And the only std history I got is warts but I got rid of that last January and it never came out since then. Please help me
