Hi, I usually masturbate around 5-6 times a week and suddenly this week I noticed that I can't get a proper erection and my penis won't get hard anymore. I'm worried that something has happened. I am only 15, and I'm worried that when I'm older, I won't be able to have intercourse with my partner, girlfriend etc. Is this a major problem, doctor? I decided to stop masturbating for 2 weeks and see how it goes. Start drinking more water and take iron pills.
