I am 20 years old. During the beginning of the year I completed the 90 day challenged and experienced the benefits most people receive on nofap. However, three months ago work and school was very overwhelming. I ended up watching porn and masturbating. Now I am 2-3 months free of porn. However, I still have ED. Before, I only had casual relationships or one night stands. Now, I have a girlfriend, my first. I can get it up with her easily initially, but when I get inside her I lose my erection. Please help, this is becoming a problem.
