Why i feel hunger after masturbation and ate alot?

It may be the pleasure associated with orgasm and anticipation of the pleasure of eating. Control your intake of food lest you gain weight to an unhealthy level. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV vaccine. Wish you good health!

You are young and both masturbation and hunger are normal part of your body function. Hunger is not related to masturbation but to other things. Exercise, be physically active and avoid junk food and masturbate at your discretion -avoiding excess- and you will be fine
