hey guys ;introducing me and asking for advice

So first of all, I'm moe and I'm an addict.... I'm an ex addict to oipoids and now trying to be an ex addict to PMO, I'm 27 and I'm in a relationship with the prettiest and most supportive girl ever, I was in rehab for a while trying to give up drugs, and a while meant a long while as I worked there for like a year after my six months period, one of the terms was no premarital terms, so I stayed single and with no sexual partner for like a year and a half, only porn and mastruabtion, also I'd like to say that I mastrubate since I was 5 years old, like daily mastruabtion and sometimes more than once, and in a way that would stop me orgasming, up until I went to rehab I had the impression I was a sex God,and I had no problem whatsoever, especially that painkillers dull the senses and makes me go like forever, but six months ago I relapsed and went back to using, I had sex with my gf during my relapse and I SUCKED, I barely could get it up, we tried again and again and I tried to take my drug use down a bit and still I had lots of hard time achieving an erection, I really donno what's wrong with me, but I am a PMO addict there's no doubt about that, in fact reading the forums here, my use of PMO is more excessive than the average user, my gf knows everything, she's even willing to go the 90 days reboot with me even though she got no problem... thing is, will I ever be OK? my morning wood became softer and I lose erections like so freaking fast.... I donno if I should see a doctor or take the 90 days challenge first and then see a doctor.... anyone with similar experience could tell me his results, as I'm really worried, thanks

 

thanks Rayz, actually I don't intend to watch porn or even mastrubate again, but like I learned in narcotics anonymous, one day at a time, what I meant by the 90 days, is without sex with my SO, I don't want her to suffer because of my mistakes
