I am 18 year old male I have redness on my penis on the glans tip urethra region for 3 months now and I consulted a dermatologist initially he prescribed me luliconazole later he prescribed chitomesh sf cream along with normal saline and said it's because of masturbating a lot I should stop doing that initially I got relief after a week but then I masturbated sometimes and the redness still doesn't go what prescriptions should I use now doctor.
