New to NoFap

Greetings NoFap Community,

I am new here, and I hope to gain some insight into methods for effective abstinence from porn and masturbation. As embarrassing as it is to say, frequent pornography use has led to problems in my sex life with my girlfriend. If I have been viewing pornography and masturbating somewhat regularly, I will have a difficult time getting and maintaining an erection while becoming intimate with my partner. As I am in my early 20s, this should not be the case. It makes her feel insecure, and it's incredibly degrading and embarrassing for me. I have been trying my best for the past week to refrain from masturbating to porn, as we both recognize a need for change in our sex life. So far the no masturbating part has been attainable for me, but I'm having a difficult time with refraining from watching porn. It's so hard to avoid it in this day and age. But I need to make changes now, or I fear my relationship may experience further problems. Any and all advice from old fapstronauts is more than welcome. Thanks, and I'm looking forward to being part of this community.
