Pls help me identify and resolve.

Pls help me identify and resolve this absurd genital and mental problem. This is impacting my life and personality since 7+ yrs. 1) I have always had boil problem in genital area since 7-8 yrs.Many atimes they are too itchy so i have to scratch alot. Even for one day if I do not not clean that area, i get boils. 2) i have developed a habit of scratching it hard in the sides of genital area esp right in such a way that i end up doing it until i have an urge to pee and somehow I have started doing it for pleasure. This has now become a habit. After scratching in this way, it pains and feels heavy. That area of my body is sufferring. I am not sure why I have this bad habit and i want to be normal like other people and this problem is creating a setback on my life.Lastly, i have a problem of urine leak. Whenever I pee, i wearing panty back, urine leaks a little on underwear. I have this problem since 4+ yrs. I don't know the reason behind this problem. Is scratching hard the reason?
