Anxiety always seems to be the answer...do you really think that anxiety is causing this pain and discomfert on a daily basis?
1. No.
2. Probably anxiety.
3. Just moisture lotion.
4. No, not an STD or a fungus.
If the pain persists, you should see the urologist again. The small red spots sound like nothing, and the wrinkling you see has no doubt always been there, but only now that you're worried are you looking so closely. Best not to.
