PIED or Anxiety ED?

Hi guys! I'm really having a hard time these days, but I'm gonna try and be brief as possible (I'm Spanish so sorry if I make any mistakes). I'm 20, I've been watching porn since I was 13 and masturbating to it, and I'm still a virgin (kind of), so the thing is: " months ago I dated a girl and the first night we were in bed (the first time I was with a girl in a bed) I could not get an erection (didn't feel much excitement). The second night was slightly better, but no erection again. When we woke up I could get an erection (since I was horny as hell) and ejaculate during a blowjob and a handjob (2 erections in a matter of 2 hours), and the next time we met, I could get an erection as well. There was no penetration in those meetings. Last week, me and a friend got along with two girls in a disco (alcohol), so we went to my friend's house and I couldn't get an erection, I didn't feel much excitement either and I was trying to get an erection, just like the two times I couldn't. (Both girls were hot tbh) The next day I masturbated at porn and could get an erection without any problem. So my question is: do I suffer from PIED or Anxiety ED? I'm really confused because the two times I was really horny I could get and erection, but I dont know if my anxiety was provoked by ED or my ED was provoked by my anxiety. I always look to make the girl feel great and maybe that's what stops me from getting horny, because I think too much. I really appreciate your time in reading this, if anybody answers and feel like there is not enough information to extract a conclusion, I'd be very glad on giving more. Greetings from Spain guys! (I'm quiting porn anyway, f**k that)

Yes you do.... but from what I can see. Your are not a worse case, but your path right now will lead to it. What you need to do now is cut porn out of your life. No Facebook, no Instagram,  no pinterest... you need to stop cold Turkey. Most of all no more masterbation.  You may be successful if you do a 90 day reboot but dont think just 90 days will cut it... this is a life time. Put it in your head that sex is more pleasurable with a woman not your hand. Save yourself for the real thing. So as of now turn away from sex... take a break from chances of any orgasim and try not to think about sexual thoughts .
