I'll be really easy on this one.

I (31M) am trying to work on my ability to full-time anal, no more front play ever again. My girlfriend (24F) is in support of this ambition, but I feel like even with her help in this I'll just relapse like I have done the previous 3 times.

The goal is, effectively, to become capable of just cumming on-demand without any real stimulation. My mental maturity levels and libido challenges make it relatively difficult to become fully aroused without some form of meaningful or connective mindset - I can still perform, but it'll usually be out of compulsion, or it'll be something I'm doing because sex is generally fun.

When I started watching hands free cumming videos a while ago, I started to look up and learn as much as I could possibly about it. I've since spent the past four or so years trying to find out how to do it, taking on the advices, performing certain rituals, etc. None of it this far has proven to work, or maybe I just need time. The longest I've gone without cumming is roughly 17 days and I want to beat that record, setting it to a permanent 91 and counting, by going through September, October and November without any front play at all.

My dream is to achieve this. I've been trying to do it for as long as I can remember, even writing this I'm recalling the time I bought my first chastity cage and was so horny wearing it that it shattered into a million pieces. I've since got a much better cage that I've started wearing a few days earlier than NoFap because I want to become accustomed to the idea that I'm not going to be playing around the front anymore, and my girlfriend will be masturbating me only anal from now on. I want to have that magical first feeling of cumming again, being able to feel like I'm actually a woman in the bedroom; never again will I have any need for my penis other than to use the bathroom or squirt violently from having my shit pushed in.

So that's the story. What's missing from all of this? How am I going to navigate my way through the next three months of no longer using my dick, let alone ever again? I've got all of the physical aspect of this down, every T crossed and every I dotted - but what mental preparation have I missed?
