Is the harm mentioned regarding masturbation only health-related?

Some may exaggerate the harms of masturbation, but the root of the harm exists and relates to health aspects, including weakened libido after marriage, and its effect on erection and premature ejaculation, which impacts the marital relationship. Islamic law prohibits that which contains corruption and harms; Allah Almighty said: "Indeed, Allah enjoins justice, and the doing of good, and generosity towards relatives, and He forbids indecency, and wickedness, and oppression. He admonishes you, that you may take heed." The corruption extends beyond health harm, and if it were of the permissible kind, the Prophet, peace be upon him, would have recommended it to the youth.
