Sir/mam, I Am Struggling From Fungal Infection. It Was In

Sir/mam, I am struggling from fungal infection. It was in 2010 when I first got fungal infection first on my penis and whole area near by then on my full butt and it spreaded below also and big rings were formed on thighs. I didn’t tell my parents then as I was very shy and didn’t knew what this was. Day by day it increased. I used powders, oil, onion paste, and Dettol and it gave me burns then also I used it as it gave some relief. It used to itch so much that I can’t control myself and took bath 1-2 times at night. I struggled till winter and I got permanent relief but it left behind stretch marks and my butt looks horrible and scary even now and whenever I sweat, I get fungal infection and it happens almost daily in the form of mild itching. Its recurring. I visited a doctor 2 times for same some days before and also got some relief by applying a cream twice daily and a tablet for 4 weeks, once and an anti-fungal powder. My thighs had also got stretch marks which itches sometimes. Please solve my queries after seeing the pics.
1.     How to treat fungal stretch marks?
2.     I cannot sit in a chair more than an hour because my butt gets sweat and it itches a lot. why It is sweating so much? I am really frustrated. Please give some solution.
3.     Near my nose it always remains red and itches until I apply a cream at night and for back acne, I was prescribed isotrrretinonn 20 for a month. And it helped for acne but not for nose. And It is running now daily at night.
