Dear
I understand your concern
Masturbation is no sin, and it is the requirement of the body upto one extent.
Body should get rid of its waste products and semen is a waste product.
Secondly, religions always provides stringent guidelines about habits which can harm our health.
These stringent guidelines are to safeguard you, not to torture you mentally.
Thirdly, moderate masturbation cannot cause you any body problem.
Fourthly, You fear god. Wrong.
We normally fear our enemies, not friends.
God is your friend, not enemy. Love him, adore him, be faithful to him.
But don't afraid of him.
Understand. Wish you good future.
