What does consistent masturbation leads to?

Normal: It will not make you infertile, make you blind, stunt your growth, cause memory loss, or make you insensitive to other people. Essentially all males and most females begin around puberty. The fact that all these foolish untruths are frequent questions here is evidence of how eager some people are to frighten young people for their own (often dark) purposes. Don't ask the impossible of anyone.
