Porn Addiction/Rebooting

Hey y’all, new to this whole thing, I’m on day no. 2 of the whole “not watching porn anymore” grind and I just have some questions and wanted to give some background on my reason for trying to stop. I’ve been out of high school for a couple years now (as I’m sure most of you know high school seems to be the big time for most guys to take a never ending death grip on their dicks), anyway spent some time after that working, not doing a whole lot socially because I just didn’t have time, and when I started college, and started having sex more frequently, I also started having fewer orgasms (during physical sex with a partner). I did some research and realized it can only be the fact that I’ve conditioned myself by watching porn for years thinking it was no big deal, and jerking off pretty frequently, sometimes I would do it once a day for a couple weeks then for two or three weeks the thought wouldn’t even cross my mind. Weird, I know. Anyway, I came across some things that said you need to just retrain your brain to be able to get off by using techniques that are easily replicated during sex, so loosening the grip, going a little slower, and not watching porn while doing it. My big question is whether or not I can still jerk off in a way that will recondition my brain to a more manageable level of stimulation, while refraining from watching porn, and if this can be done successfully.
My inability to orgasm during sex with any of the women I’m with has put a bit of a dark tint on our relationships, they usually think it was their fault and they think they aren’t good enough in bed or not attractive enough, which I assure them could not be further from the truth. Anyway, it’s hard to have a good sex life without being able to finish during the actual sex.

 

What about sex? I feel confident that maybe if I can abstain from both porn and jerking off, I could finish more easily during physical sex, but I don’t want to rush anything. I also want to continue having sex, and the girl I have been seeing more exclusively and I have talked about it and she knows it isn’t her fault and we both want to continue, is that going to be bad for my rebooting process or could it help if I am ONLY having sex and abstaining from pmo
