If someone can help me with advice, I will be so greatful.

Are you using masturbation to reset because of the post nut clarity then? This isn't the way as you probably know. Yes you may have it in your mind longer if you don't act on it but that's why people consider it a fight and a struggle, and even though there are things you might do on other levels sometimes you do have to resist.

Without knowing anything else about you it's really hard to say what other things you might try, but overall you can't just flip a switch and get rid of a thought. It may have to be as simple as something like setting a goal of not acting out on it for 5 minutes. That's not a small thing if you are not trying to distract yourself and just sit with the feeling and/or the thought.

Have you been diagnosed with OCD or is it your own understanding it is OCD?

And the thought you are a pedo doesn't make you a pedo, any more than the thought anyone is having sex means they are having sex. I hope that's clear and helpful.

 

Try to do something physical everyday it's more easy to control the body than the mind. A healthy body is the prelude to a healthy mind, they are connected.
