Hello,
Welcome to Healthcaremagic.
I had gone through your query and understand your concern
Masturbation is as healthy and normal.
But as with other behaviors, when over-practiced or done in an excessive, compulsive manner, it can lead to both psychological and physiological imbalances in your body.
Due to psychological affect you may have both memory issues and
weight loss.
Keep in mind that, Masturbation is normal when it is few times in a week or month.
But i advise you to concentrate on other things and life.
Have healthy diet and spend time in other recreation activities like indoor and out door games.
Masturbation have no ill effects on health and sexual performance.
Don't worry, you will gain control on your thoughts and fear over time.
Hope this helps.
Please reply for further queries.
Wishing you good health.
