Sorry for late reply and inconvenience.
Thanks for all these additional information.
I understand your concern.
I have reviewed your picture and as you describe possible causes may include Irritant balanoposthitis/Candidal balanoposthitis.
This is an inflammatory reaction of the glans penis and/or surrounding skin to smegma - which is the natural secretion from glands around the glans penis.
Excessive moisture can also contribute to fungal infection also.
When the spots come apply a mixture of 1% Cortizone cream and Bacitracin ointment immediately over the spots - this should take care of them in a few hours.
Also take OTC Motrin and Claritin for few days.
You should use OTC Abzorb powder.
While bathing avoid using soaps on the penis, instead use a soap free cleanser to gently clean the glans penis and the surrounding skin everyday.
Apply a moisturizer like cetaphil lotion there immediately after toweling up.
Avoid very hot water while bathing as this can again irritate the sensitive skin down there.
Wear loose fitted cotton clothes to prevent friction.
If your symptoms'll persist then see a dermatologist for further evaluation and management.
Let me know if you have any further query so we can discuss it thoroughly in every aspect.
