Balinitis fungal infection. Is visible.

The foreskin of my penis got sored and was paining at night while sleeping a month ago. After checking online I understood it is Balinitis. I started cleaning it with water every time I used toilet, then understood I shouldn't do that I stopped cleaning with water every time. Now only clean with warm water while bathing, use a thin face cleaning paper napkin to dry it. It got reduced after I used coconut oil, but it keeps coming back again. Foreskin becomes sore a bit red, white fluid comes from under the foreskin, doesn't pain now. Haven't used any medicines, only coconut oil. Please suggest me how to cure it completely. I am 30 m, unmarried, doesn't have Diabetes, does workout and follows healthy diet and doesn't eat much sugar. I have attached 2 photos, in the 1st picture a small white patch is visible.
