I'm afraid I have no idea what you are referring to. Chemicals applied to the skin can't produce long-term odor problems. I suspect that the sensation and the smell are the result of your thinking and worrying about the penis. If people next to you say them smell something funny, it doesn't necessarily mean the smell comes from the penis. Most people have strong-smelling urine in the morning, because urine is concentrated then. Smell would not have anything to do with "controlling the flow" of urine.
In other words, your symptoms do not add up or make sense. I advise you to get definitive opinions from your urologist and perhaps a medical doctor who tests urine. If they can't confirm an abnormality, you will need to give serious consideration to seeking therapy for abnormal body sensations. I have no doubt you will not find that suggestion satisfactory, but I urge you to consider it anyway.
Best.

I would advise you to DRASTICALLY increase your intake of water to about ten glasses a day.
Over the course of a week, see if this does the trick.
I suppose you should also consult a urologist as well.It's probably no harm
