Rewiring Help Please

Hello everyone. I hope everyone is doing well and enjoying great sessions. So actually I'm not a newbie I have been doing prostate play for over a year now. I have spent close to $3,500 on various different kind of sex toys. I have the aneros helix syn v, vice 2 normal plastic helix and mgx and eupho and a progasm jr. Other than that I have almost any toy you can imagine like njoy njoy plug and basically any word that was recommended on prostate play subreddit on Reddit. I have tried rotating toys I have tried almost everything very sincerely but I absolutely just do not feel anything and the starting it was discomfort but now I don't feel discomfort if I do it regularly but if I take a break like a week or 2 discomfort on insertion returns. The discomfort is not like pain but just kind of irritation in the rectum. 

I think I just want sad a hands-free wet orgasm with the toy called phanxy wave motion a few months ago and that is all. I have been trying to reach it again but no results. 

I have read a lot of the discussion series and I know that I am not supposed to aim for anything or teach anything or try anything. I have been abstaining for orgasms for like weeks in a row trying to make the frustrated experience more pleasurable but now I kind of feel like I'm just wasting my life because you only have so much time on this planet and you are only going to get so much orgasms and if you are not even enjoying that to read something that is probably not possible I think it's just a waste of time and energy. 

I really really want to do chief any kind of pleasure no matter how certain from aneros but that has not been happening. I have tried the crimson Wolf method I have tried to do nothing method but I think the problem is that you need to be somewhat rewired in order to achieve anything from those things I just do not know how I can rewire. I have not been able to quit porn but there have been times that where I haven't watched porn for a few weeks to months at a stretch but I haven't been able to quit it completely. Some of you might say that that might be a reason holding me back but I don't think I can really quit it. 

I do not know how to really rewire that is effective. I just think my brain is broken because I have not been able to rewire. Please someone tell me it gets better because I just cannot keep going like this I feel like I'm just going nowhere. I haven't particularly used aneros a lot but I have at least used it at least once in 2 weeks. But I have made sure to use some other toy at least twice a week so basically I'm having prostate play twice a week for the past year and I think my condition is still the same as the day I started. I know that I am not supposed to chase anything I am supposed to enjoy the journey but imagine this if you have had like hundreds of sessions but receive absolutely zero  pleasure and even sometimes mild discomfort would you still keep going? 

I just think that I was since I was 13 I have been watching porn a lot and masturbating now I am 20 and I think years of that has destroyed my brain and desensitized to me to such an extent that I rely upon those things too achieve any kind of satisfaction.

I do not really know where to go from here on so if there's anyone who has had like a similar journey in the starting but has had gained success later would you please share any exercises that I might perform or any tips that might help me to get rewired because I think the problem here is the reviring. I have also ordered a chastity cage so that I do not touch myself whatsoever. 

Thank you everyone in advance you guys are an awesome community and you are really nice people who help each other even if you don't get anything out of it and I really love such a positive and impactful community and I love being a part of it thanks for being here.
