Dark genital area and probably infection

My skin color of body or face is very fair but my penis and balls are extremly dark.    Also some part of skin on my thigh is extremly sensitive. (Thigh area around genitals). The skin there is very thin and looks like it can get easkily peeled off.  I want to whiten my private parts so that it matches my normal skin tone. This really is causing confidence issues in me. Can i use deepiwhite cream or kojivit cream? Which cream will be best for use without any side effects. ? I do not have any itching in my private parts or thighs. May be there is a fungal infection on thigh area.. i am not sure about.  But i dont think there is any infection on the skin of penis and balls..looks like plain hyperpigmentation issue for me.   Can i use clocip powder for thighs and skin whitning cream deepiwhite or kojivit (please suggest best and cheapest one).   Please suggest your views and medications for my problem.
