Does masturbation is cause of hair loss or skinny body or acne?

No: If masturbation caused this, most of the population would be thin and bald with acne. Best wishes.

Masturbation: Despite old wives tales about going blind or growing hair on your palms, masturbation does not cause any change in your appearance, hair patterns, or stature.

Nope: In short, no to all the above. Sadly, in some cultures these scare tactics commonly are used to discourage this completely normal human act.

None of them: I am sorry people still are telling untruths to frighten them. Manage your acne with medications like benzoyl peroxide. Male hair loss is genetic. You can build your muscles. You are almost a grown man and I hope you will be discerning and not troubled by foolish scare stories.
