I have been masturbating since I was

Patient: I have been masturbating since I was twelve because of influence of peers and cousins. I don’t know the frequency but now my penis isn’t growing and a lot of precum come out whenever my penis is stimulated. I can also see my veins. As rarely as I watch porn my penis can stand for five mintutes until there is a leakage. I also noticed my concentration and focus going away when precum leaks. I have also noticed I have slurred speech and the incorrect pronunciation of some words. I am also not smart.As much as I try to by reading books, solving optional math questions and iq challenges other people are quicker in thinking. I feel like masturbation has done this to me. I want to know if there is anything I could do to bring me back to the state before masturbation. I want to be normal.
