I m 18 years old, and I ve been masturbating since I was 14, I m a very good student, and a perfect listener, whatsoever lately, especially at this moment when I am watching movies, I forget the names of the characters so fast, whilst I go through the names over ten times in the movie, for some reason I am starting to feel like I m having problems concentrating, also I started forgetting stuff very quickly, names to be precise, I masturbate once a day or twice, or even none at some cases, could you tell me whats wrong, and give me one solution I could devote myself to? thanks.
