As I said in the title, I've discovered a single red bump underneath my penis at the base of the shaft. It just formed there two days ago and I'm a little worried. I had unprotected sex once about five months ago I think, and haven't had a bump like this yet. I have, however had some cloudy urine and a little difficulty finishing a few (maybe three) times before but I didn't think much of it. I googled it and decided it was probably a UTI but now I'm not sure. Today the red bump has gotten a little bit smaller, but the texture of the skin on the bump looks a little "raw" now in a way. Maybe I'm making it up, I don't know.
Can anyone give me advice? I'm going to get an STD screening as soon as I can but I have some transportation issues right now.
Thanks
