Hi mate, I had the same problem as you. The cam chat had me quite stuck, especially since I already had contacts that attracted me and I wanted to repeat.
In my case, what helped me was the motivation to experience my real sexuality again. I ended up understanding that while I was very excited about the experience on cam, there was a point where that felt incomplete (I think that anyone who has experienced a good sexuality ever understands this).
And there was something that helped me a lot. Accept that sexuality is something less explosive than the experience on the cam. I mean, in my case I had to understand and give up the fantasy that you can have sex with everyone you want, at the time you want. I think that's the temptation of cam chat.
Deep down you know that real sex more more pleasant, but it also takes more time. I say this because in my case I'm single, so you know you have to move, to contact someone, give time to the situation, run the risk of being rejected, and especially that is not immediate.
That's my experience, I've been without PMO for 110 days. I regained my desire, I notice it continuously, and well, now looking to find someone.
I wish you the best. It is difficult, but if there is a good motivation it can be. Hugs
