Does anyone know how to do erp for yourself? How should I start?

Can I hear some examples of specific parts of ERP that has helped you? I've been doing talk therapy for a few years and the major issue I have with it is that I already have analyzed all of my problems from every angle, so I'm kind of just sitting there yapping about it for an hour. I need solutions and things that make me feel better.

I’m starting NOCD. I had several years of cbt as a child (well over 20 years ago) and I see a trauma therapist. But now I’ll be seeking further help for OCD and just really scared. CBT wasn’t helpful for me. How has ERP been helpful for you? Do you feel like you’ll finally get your life back? I’m consumed by my obsessions 😢 Would love others feedback if ERP helped you ❤️

How long should I do ERP, so that my brain gets used to it, not to say tired?! I've been working for about three months, but everything still seems vivid in my head, there are even vulgar words in detail... since the sexual topic is both a groinal and a feeling that I want to touch myself. It's mostly related to faces and genitals, so how exactly can that go, if it's emphasized that sex pictures in themselves give that feeling, whoever is in them?
