Hello everybody, I'm doing nofap for so long, since the ending of winter and after all this time I can't get harder in bed and my girlfriend is very disappointed in me. I started eating healthier, going to the gym over 3 times a week and gave up to a lot of bad habbits like drinking, smoking and I still don't know how to improve this. Guys, I'm desperate and I hate the situation. If someone can help me I will be very grateful. Thanks!
