approaching 50 days

now that I'm about to hit the 50 days mark, I can give you some details of the benefits I'm experiencing but also of some weird things and doubts. Right now I am in a long-distance relationship but we'll be together from December on, then no more distance between us. For this reason, I'm doing NoFap hard mode. I've never orgasmed over the past 47 days and not even edged. Sometimes, particularly in the morning, I'm very horny and I'd like to rub my penis against the mattress but I stop to stop right immediately. I picked some porn videos three times or so but it was softcore and I managed to not touch myself. I don't want to do it again, though. The main issue why I started NoFap is because I may be slightly addicted to porn but my main issue is the DE: I've never come inside a woman and this has damaged some of my past serious relationship. I've always masturbated a lot (sometimes even 5/6 or more times a day) and before 16/17 I used to orgasm thorough dry humping

Benefits:
1) less social anxiety: I care less and less of what other people think of me; more extroverted and less shy
2) better skin and general look
3) more energetic, need less hours of sleep
4) larger penis and balls, my reproductive organs look better and majestic and I'm very proud of this
5) more ambitious, I set goals for myself and I want to achieve them
6) music feels better but I can also notice more all the beauty around me
7) my hair and beard have been growing faster
8) the voice is deeper and I have an overall more masculine demeanor
9) I'm more content with myself. I've wasted so many hours with porn and meaningless masturbation, throwing away important years and likely dates with gorgeous girls because when you masturbate heavily you don't feel very much like approaching girls and dating. Also I had lost direction in life.

weird things
1) between day 20 and 35 I've had a tingling sensation in my balls and penis particularly when I wear tight pants
2) I've never had a wet dream in my entire life. Now that I'm approaching day 50, I'm really questioning why I haven't had one so far and how it is like to have them
3) as I said I'm in a relationship but I'm getting a bit nervous of not being able to cum inside her. She knows about my problem and I told her I wouldn't touch myself in order to make it more likely and I don't want to disappoint her. The thing is that I'm not sure if my DE is caused by "death grip" and years of heavy masturbation (often with porn, but with many months even without porn). I'd say that I recurred to porn to and masturbation to come because I do enjoy sex, but not being able to ejaculate makes it somehow less terrific to me. Also, I'm questioning whether my prone masturbation against hard surfaces has made me any long term damages. Don't think so, but you never know.
4) my hair loss has not improved, possibly get worse even though I put minoxidil over my scalp
5) I don't feel like I'm likely to relapse but you should never let your guard down. Moreover, I'll have sex with my girl from day 62 to day 70 because she's visiting me. Hope I won't have the dreaded Chaser effect. I'm not planning to fap again. I'll rather have sex with my girlfriend and that's it.

 

thank you guys! Do you believe my delayed ejaculation is related to death grip and could solve after 90/100 days of complete abstinence aside from one week of sex with my GF?
