23yo newbie here

Hello everyone. I am a 23 yo man. I have been masturbating and watching erotic videos almost every day since I was 14. I have an inflation fetish and almost always I watch videos related to it. My current sexual partner is my first one, we started having sex about 3 month ago, and, since then, I have never had an orgasm during sex. This is the problem I want to solve here. I am too used to intense stimulation from my palm and to weird fantasies about breast expansion or body inflation. I want to learn to appreciate the real sex with real person, because I have very few sensations from my genitals during sex. I spend around 15-20 minutes on masturbation every day. I want to make a better use of my time and become more productive. I want my fetish to become weaker and stop dominating my sexual desires.

I visited a doctor 2 months ago, and he told me I must stop masturbating. I have not done it so far, but I hope with the help of nofap community I will do it.

I will stop watching any porn, any erotic videos, any inflation-related videos. I will stop masturbating, but I leave having sex with my partner as available option. My target is 90 days. Today (2022-08-27) is day 0.
