I think your condition has been solved and what you have is a consecuence of the use of the steroid creams. Steroid creams do more harm than good. Happened to me and I have read many stories of members going through the same. Leave your penis alone don't pay so much attention to it and let the skin repair by itself.
You can also read my prior comments. The home remedies were given to me by a doctor didn't work for me but have been very useful for other members. Ihope you get better
I went through almost the same things as you, my story is long as well. I will try to make it short:
Same synptoms, went to many doctors, MD, urologist, etc.. many tests, many medications, spent so much money and my life was hell for 1.5 years. I finally was dignosed with balanophostitis wich was redness of the glans and inflammation of the foreskin. The use of steroids creams left me with a red and very thin skin. None of the medications did any good to me. The last urologist I went suggested me to do a circumsicion, because he said that the foreskin was creating the problems for the moist and humed conditions that was creating the growth of fungus and yeast. After trying everything I went for the surgery, my irritations heal as the same time I was healing from the surgery. I have been cut already for 3 years and my penis still looks healthy. I am not suggesting you circumsicion, it is a decision you have to take along with your doctor. I still believe that circumsicion has to only be done for medical reasons and that the normal state of a penis is to have a foreskin. It worked for me, I miss my foreskin but I'm happy that I don't have those irritations no more. Try to do the following:
Spread plain yoghourt on your penis 2 times a day.
Dilute 2 teaspoons of white vinegar in a glass of water and soak your penis with that 2 times a day, morning and nights.
Air dry your penis after every shower.
Please do not use those steroids creams no more.
Ask your doctor if Nystatin cream will be good for you.
A picture of your condition will be of a lot of help to see if that looks the same of what I had. Any questions? I will be glad to answer. Your age?
