Examples of intrusive thoughts?

I don’t know how to explain this so I’ll do it to the best of my ability. Does anyone experience “co-intrusive” thoughts that try to negatively support the initial intrusive thought? Example: Me: “Thank God I never acted on (scary intrusive thought) & I’m getting better!” Intrusive thought: “What a shame you didn’t” These types of things send me into a spiral. It makes me think that it could lead to a desire instead of staying a fear. Like an intrusive disappointment that I didn’t follow through with the thought? It’s been a long fear/obsession & I think my OCD is trying to trick me that the only satisfaction would be to act on the thought. (I know that’s bs) But IS that why it sends me the negative co-intrusive thoughts? That’s the only explanation that makes sense. Then I wonder is it something else? Am I a grenade waiting to explode??? I simply cannot relax in any moment because I think what’s the use if I’m just going to (xyz) one day?

I need advice for intrusive thoughts. I used to feel like I could handle them. They weren’t nearly as bad as the things that related to my actual life. But now, I’m suffering. I haven’t had a sexual experience in over a year that didn’t involve constant intrusive thoughts. Most are somehow related to kids and I keep chasing off the thoughts but it’s so bad. I know you’re supposed to ignore them but I don’t know how I can just ignore that and continue what I’m doing. But they’re coming on stronger. I had one earlier I could not get rid of just as things finished so the thought came on strongly just before my orgasm hit and now I feel absolutely disgusting. I hated the thought and I know it’s not me and it was not enjoyable but it still feels like I was getting off to it. I feel sick. I’m so fucking tired of these thoughts. They’re in my every day life too and it’s all the time. I just want it to stop but ignoring it feels so wrong. What should I do?

Please how can an intrusive thought be distinguished from our own thoughts ?
