I would cut out all sexual stimulation other than what your girlfriend can offer you. I seem to have an unconventional opinion with playing with fetishes, but I don't think it makes a difference. If you're getting the fetish sexual satisfaction from your girlfriend, and not porn, then I don't see the harm. Our PIED problems are porn related, not fetish related. And I dealt with a good bit of the 60-70% erections where I would have to squeeze the base of my dick to get it full enough to slide in. Honestly, just keep trying that method. Sometimes it wasn't fully enjoyable for me, but I kept trudging through those 60-70% erections and forcing myself to perform even with half-assed erections, and they eventually turned into 100% erections. Even if you aren't fully hard, your brain will eventually relearn that it "likes" the vagina, and you will start seeing improvements with your erections. It sounds sorta brutal to say "force it", but honestly how else is your brain going to learn or become used to a vagina? It worked for me, anyways. A question I have- how long have you been rewiring for? In my opinion, rebooting alone is sometimes not enough. I am definitely rewired to more than just my girlfriend now. Real girls in general turn me on now! For instance, I can look at a girl I find incredibly sexy and feel a physical need to masturbate. It makes sense what you're speculating, but one girl was enough for me to reintroduce myself to normal arousal!
