Gay man advice and accountability

25 year old gay man. I've been masturbating to porn, instagram, twitter, and literotica ever since I started masturbating at age 13. I never masturbate without the Internet, mostly on my phone. I think my triggers are boredom and low self-esteem, as well as trouble getting to sleep. I realised it was an issue about 3 years ago when I wasn't able to perform with men and the act of sex just makes me really anxious. I masturbate at least 2 or 3 times a day and it takes up so much of my time.

I need to stop this addiction so that I can build myself up into a better, more productive person who can build a healthy relationship with other men.

The thought of this journey is scary. I have attempted it multiple times before but only ever got to 14 days of no orgasm, but even then I was watching porn from day 5. I've tried installing blockers on my phone, but I end up just disabling them to go back to porn.

Any advice on activities I can start to fill my time to replace the time I PMO would be appreciated.

Also would appreciate an accountability partner, preferably my age and gay and based in the UK - can chat on here or WhatsApp.

Thanks all x
