Hello, Masturbation in excess can affect your health adversely for some time, but it will never be chronic. Moreover, masturbation will not affect your penis length. The small penis size is not due to masturbation and as of now you cannot increase your penis length. Therefore, be satisfied with what you have and don't waste money on treatment for the same. Therefore, I suggest consulting a psychologist for counseling. Hope I have answered your query. Let me know if I can assist you further.
