I have 6.3 foot height and weight 88.10 and still seeing same fat stomach. why is dis happening so. does asturbation or crunches haveany impactwith it?

Praiseworthy goal: You're reaching your physical peak. Your weight is calories in versus calories out. You can do crunches forever and it won't affect your abdominal fat. Self-entertainment is a good thing, preparing you for adult life, and isn't the problem. You want to adjust your attitude toward greasy / sugary / salty food (stop buying it & learn to enjoy other things) and find aerobic fitness you enjoy.

Masturbation is: Likely not associated with your stomach size. There's no such thing as natural spot fat loss. You need to lose weight in general ; a certain % will be abdominal fat. Eat healthfully ; be physically active. Calories burned must > calories consumed. To tighten ab's do crunches, reverse crunches, exercise ball crunches, pelvic thrusts, lying leg raises, side bridge ; “bicycling” exercise on your >.
