A Slightly Different Story and an Appeal for Advice

Hello all. I'm 18 years old and brand new here. I made an account with NoFap, after reading through a lot of articles and forum posts here, with the primary intention of posting this:
I think I can say with some certainty that I’m no longer actively addicted to porn. I watched porn pretty consistently, with occasional gaps, from the age of 10 to the age of 17. During this time, I also developed a style of masturbation that made me lose interest in jerking off: this was simulating sexual intercourse by placing two pillows on top of one another. That abnormal but sensationally intense style may contribute to the ED I began experiencing between 16 and 18. In addition to ED, which I have been crediting to porn, I have also been having an unfortunate case of PE. Both of these things are incredibly anxiety-and-shame-inducing and frustrating. Now at 18, I have not watched any pornography and had no cravings in over a month; before then, late-night porn/camsite sessions were already few and far between (and had been increasingly so for several months.) I would still find myself in an MO pattern almost every night before sleeping with rare exception, often in the mornings as well; most of the time, however, these masturbation sessions would be supplemented with my long-distance girlfriend’s nudes and screenshots of very sexual conversations we’ve had. However, on May 15 2018, I was still finding it difficult to get fully and functionally hard, even when my girlfriend, visiting for the first time in a year, was going down on me. In an effort to fix this problem, starting on June 11th, I radically cut back on masturbating and orgasming, recognizing how regularly I was doing it beforehand. I kept it to under 5 orgasms in a 10-day time period. At this time, however, I was still using the pillow technique. Starting on June 21st, I stopped orgasming and masturbating almost completely. On 3 separate occasions during this period I did masturbate using only my hand – a technique I used very rarely before, if at all – using 3 new nudes my girlfriend sent.

I believe my situation is somewhat different than most of those on NoFap and YBOP and other forums for a couple reasons. The first of these is that I am not coming straight off a hardcore porn addiction and I no longer find it difficult to go weeks or even months without traditional internet porn at all. I have been winding down my use without any specific intention of rebooting for the last year; it is not difficult for me to stop watching pornography cold turkey because I essentially already have. I lost interest in it. The biggest challenge for me is to stop masturbating and ejaculating, because I did it with daily regularity, began to feel unhealthy and perverted about it. The second of these is that I have a long-distance girlfriend I love very much and get to see very rarely; the lack of sex we’re able to have is combatted by occasional intense sexting, with both pictures and lots of incredibly suggestive language. This is probably the biggest means by which I get off now. The third of these reasons is the style by which I’ve masturbated for the last 8 years: the pillow technique, which I believe has contributed to desensitization. Although I’m sure it’s been done, I have yet to hear of anyone else say anything about consistently using this style.

These situational differences make it hard for me to relate to many of the stories on NoFap. Yes, I’m experiencing erectile dysfunction and yes, I have a history of porn use. However, the porn use isn’t recent. This confuses me and leads me to think that maybe the erectile dysfunction is an effect of performance anxiety combined with excessive simulatory masturbation. I will be seeing my girlfriend in a month from July 26-July 30. My plan going forward is to stop looking at/masturbating to her nudes, continue to abstain from orgasm and pornography, begin abstaining entirely from masturbating, as well as order a 30-day supply of the herbal supplement VigRx beginning in the first 2 weeks of July (although I've read varying reports to the time it takes for VigRx to become effective.) To aide in alleviating performance anxiety and my chronic depressive tendencies as a possible cause, I will begin regularly taking St. John’s Wort, as well as doing a daily meditation and light workouts throughout my day. Ideally, once I resume masturbation at whatever time that I do, I will only use my hand, having resensitized my penis, and primarily use mental fantasies (something I hardly ever do anymore) about my girlfriend as stimulation, rather than pictures of her. However, I don’t anticipate resuming especially soon and certainly not before I see her at the July 26-30 point.

Does anyone have thoughts, recommendations, insights into how I can better my situation and perform the best I can for the girl I love at the end of July? I think I need someone other than myself to weigh in on the factors here and, at this point, I'd appreciate a little hope and encouragement. Thank you so much.
