Suggest Treatment For Redness, Soreness And Cracking Of The Foreskin

I have for three to four years now experienced redness, soreness, cracking of the foreskin on my penis. Can occur after intercourse (can be very painful), or, without sex. Dr. prescribed a prescription chlomitrazole ointment/cream. Told me to use it twice a day for 3 to five days. He also gave me a dose of oral yeast infection medication (diflucan). I have done this procedure I don t know how many times. Went to urologist and was told I was diabetic...therefore the cause of the problem. I was tested twice and no, I am not diabetic. He then tells me to use bacitracin ointment to heal the cracks. I am now trying (on my own) an OTC hydrocortisone cream (one week). Seems to be helping, but, afraid to even try sex. Any suggestions would be most appreciated!
