I read the definition of intrusive thoughts are "Intrusive thoughts are unwanted thoughts that can pop into our heads without warning, at any time. They're often repetitive – with the same kind of thought cropping up again and again – and they can be disturbing or even distressing." But my thoughts aren't as pop ups, they are just very very very disturbing. Honestly 90% of my OCD is just fear that I'm a pedophile, not intrusive thoughts, just that FEAR.

any thought that is unwanted is inteuive. they don’t always have to be pop ups, you can just ruminate on that one theme for hours & have reoccurring thoughts. this would be OCD, obsessively thinking of the fear, doing compulsions like searching for answers, and finding reassurance, just to restart the cycle. normal people have intrusive thoughts all the time, but what makes people with OCD different is we obsess over the intrusive thoughts & affect the quality of our lives. :) i hope this helps.
