Irritated foreskin/glans

I have had a problem with my foreskin being too dry. A few years back this had lead to my glans (glands) and foreskin to become irritated. When I saw a dermatologist, he prescribed a hydrocortisone cream and recommended to use a mild moisturizing cream. This helped and I was a happy man again. Now, a few years later, the problem came up again. This time the cortisone cream did not help. It did reduce the rash, but the foreskin became pale and when I washed it, underneath the pale layer, the red skin came back. I went to a different doctor, as I had moved to another country. The doctor checked for fungal infection, but the test was negative. Then she prescribed ketoconazole, which did help, but what remained was a sensitivity of the foreskin and glans (glands) that was unpleasant. I went back to my inital doctor, who also said that there was no infection and prescribed hydrocortisone again and recommended using a lubricant on water basis. The hydrocortisone showed the same result as initially, but the lubricant helped. The glans (glands) and foreskin took nearly normal color as before and the irritation became less. But, my penis is still extremely sensitive during intercourse or masturbation. It is also not pleasantly sensitive, there is an itching component to it. I am really worried that I will never have proper sex again in my life. Anyone have some advice?
