Welcome to HCM
We understand your concerns
I went through your description. I suggest you not to worry much. The odor at the head of your penis was always there. Before affair, during affair, after affair. You noticed it only after you broke up. That is the fact. Once found, you started worrying about the odor and you started washing your penis and started worrying. Slowly the odor became obsessive. In my opinion the odor is just in your thoughts (if you are sure that you are keeping the head of the penis thoroughly clean). Or else try to keep it clean.
