Nightly Masturbation, No Porn, No Fantasy

So like many of you guys I’m sure, i come up with a new philosophy towards porn and masturbation every couple weeks. The last one i tried was no porn, no masturbation at all, only sex with my girlfriend. I found that having to depend on my gf for sexual satisfaction was causing me frustration and resentment. I actually ended up visiting a strip club as my bright idea to cheat the system and relapsed that night.
Now i have begun masturbating on a nightly basis without porn or any kind of fantasy. It’s certainly not easy but i feel a lot better. My libido is lower so i have sexual thoughts much less often and my friendship with my gf is much closer.
My question for you guys is has anyone had success with this? One thing i worry about is how I’ll perform during sex if my libido is being kept low. I imagine that being with her will much more exciting than being alone with my eyes closed. I am speaking as a 29 year who has experienced e.d. as a result(in my opinion) of my compulsive use of pornography.
