I am 22 now. From 13 years of age I started masturbating. I daily masturbate( around two times/day). I have developed the habit of masturbating daily.
What I want to know is-
I) Can it impose an adverse effect on my future life and career?
II) Lately I am experiencing some concentration issues. Can this be somehow related with my action for the last nine years?
III) Can my average testosterone level fall due to this?
IV) CAN THERE BE ANY OTHER SIDE EFFECTS LIKE GOING DYSFUNCTIONAL, VISION LOSS, MENTAL PROBLEMS, ETC???!!!
V) In all, can this frequency destroy my life?
