Why doesn't masturbation or sex make the penis grow?
I’ve read several statements like: “Nothing in the Newbie Routine caused this kind of damage. Masturbation, and /or rough intercourse is harder on your dick than jelqing, or manual stretches.”.
This seems like flawed logic to me. If sex or masturbation doesn’t make the dick grow but jelqing does, then of course jelqing stimulates (hurts) the penis in a different way than sex and masturbation. Thus it might cause damage that sex or masturbation doesn’t cause.
Am I correct in my arguments against the statement that “sex is rougher, therefore jelqing can’t cause damage”?
