Its about loneliness, and that is not gonna go away.

Just my experience, if you do relate, this might help you. Like it says in the title, atleast for me, it has been about loneliness. Not as in surviving alone. But at some stage everybody wants to have a partner (gf/spouse) to just be comfortable with. All these years I was socially awkward, felt weird when my friends used to flirt with other girls, or even if a girl spoke to me it was about studies/movies/jokes. Trying my best to not be vulnerable to that type of stuff coz my head was messed up with P.
There's so much to write about, but mainly that what you see online is not what it is in the real life. A girl is not gonna fall head over heels for you just for you existing. And S is not about (mostly) physical pleasure. Its a connection with the other person, that you really like so much. Once you realise how big the act itself is, the somebody is willing to be intimate and vulnerable with you, you will realise how shallow all this internet crap is. And you will crave a real connection with someone. Apart from the physical and psychological benefits, the basis of your addiction needs to heal. And that is only possible when you introspect and work on yourself. It is not easy, god knows how simple it is to give into those urges at times. But trust me, this realization alone made me despise how I was consuming the bad stuff all this while and trying to knock off the effects thinking I'm alright. No I am not. Neither are you. But this is the first step to healing, and you know innately that something doesn't sit right with your habit. In my case, I want to have real relationships, not some mind-numbing self-serving addiction that does the job. Because I know that the real thing will have a lasting impact. I pray that you find the cause of your addiction and address it, in whatever way you can (speak to someone/write about it/rant like me on this forum). But get it out of your system and face it. Its not for other people, but for you. And get busy doing/building something. You'll realise that there are a billion other things worthy of your energy that this stupid vile addiction.
Please reach out (myself included, although I'm consciously not regularly active), praying for your success
