New To This, 18 Years Of Age And I Think I Have PIED ?

So basically I’ve just joined this Community, before I would just read off of other people’s threads but I took lead to actually make an account. Basically I started PMO when I was 16 I believe and I am 18 now, there were times when I would stop doing it because I just thought it was a bad habit so I had gaps sometimes but not long ones. Since I got older I did it more and more and had sex with 2 people, the first encounter was with a 23 year old and at first I was nervous and got soft but she got me back up and after that many times I wouldn’t have a problem getting hard and would have a(n) HARD erection, no problems with her at all just the first time I was nervous so I get that. 7 months no sex, no anything, just PMO and I did it once every day or sometimes every other night before I went to sleep. I didn’t PMO a lot because of guilt but I did it once everyday/ever other day and never would do it twice, rarely did that. Now I’m with my current girlfriend and the first time I had sex with her I wasn’t very hard and she had to give oral to get me back up and my executions wasn’t very hard, I was surprised to actually do it with her but we switched positions and got soft and couldn’t finish, funny too because I lasted longer with her and didn’t finish than I did with the 23 year old so I’m guessing DE. Couple weeks ago I tried and couldn’t get hard at all, and that’s when I discovered NOFAP and right now I’m 24 days in, just got oral twice but I wouldn’t count it as a relapse, didn’t O. Since 24 days I have no urges at all to PMO to porn like AT ALL and I wouldn’t say flatline because I get occasional boners randomly and I get MW, so I think I’m healing so fast because I only PMO for only 2 years not very long. But now when I try with my girl I get soft, like my erections are like 60% maybe more sometimes. So I may be thinking I have performance anxiety but ever since 24 days, my erections are getting better and lasting a little bit longer but I have yet to try with my current girlfriend right now. Sorry for this long thread, I just kinda need some advice ? I have no urges to masturbate to porn at all and I think I won’t for a while, I know it sounds delusional but seriously think I can do it.
