I'm a 18 year old male and I've noticed that my erections are getting weaker. I started masturbating around 2-3 years ago and now my erection is at 80 to 90%. Also I need to constantly stimulate my dick or else my erection fades quickly. My guess is that this is due to excess masturbation because I jerk off like 2 times a day everyday while watching porn. If I stop masturbating for a week or two I get 100% erection. Pls give me some advice on how to stop watching porn and stop masturbating
