What causes ocd?

Trying not to seek reassurance, but rather connect the dots on my OCD and possible reasons as to why I am the way I am. I have severe OCD (or at least I hope I do) mainly surrounding POCD. I've had symptoms of OCD the majority of my life but this theme has come up more recently. When I was a kid, and i'm talking 6-7, I was first exposed to some really gross adult content online. It was introduced to me by a friend of mine around the same age of me. I saw some really disgusting things that a 6-7 year old should definitely not see. This was not a one time occurrence, as I had been exposed to taboo topics online years to come after that, such as the same friend introducing me to Omegle... And i'm sure you can imagine how that went, theres a lot of genuinely disgusting human beings on there. Coming back to the reason for making this post; is it possible to early exposure to this content could be one of the reasons I struggle with POCD? It genuinely scares me to death because you hear that real p*dos dealt with simular situations when they were kids, so thats kind of making me feel that this could be more than OCD, and I could be a genuinely bad person. My POCD feels so real, that at times i'm fully convinced its not OCD. Sometimes I can't even distinguish the feelings of attraction between a younger person and an older person, except for the feeling of anxiety and fear. Its really hard to explain without going into detail, but it just feels so real. Some feedback on this would be great, thank you all.

This list by ai gives a good summary of my symptoms. Does it resemble OCD or is it something else? 1. Compulsions (OCD-specific behaviors): • Feeling the need to flex or contract muscles an even number of times, equally on both sides of your body. • Needing to reverse actions (for example, if you roll your eyes or trace a line with your finger, you feel compelled to do it again in the exact opposite way). 2. Intrusive Thoughts (OCD-specific ruminations): • Daydreaming about people you care about getting hurt (e.g., school shooting, injury, or kidnapping). • Sometimes feeling like you might want something bad to happen to someone you find attractive—possibly because of a desire to help or save them, though it’s confusing. • These thoughts can sometimes provide a twisted sense of relief while remaining distressing and confusing. 3. Sexual Orientation OCD: • Experiencing confusion or doubt about your sexual orientation. 4. Contamination Thoughts: • Feeling like things are contaminated, especially after touching something gross. 5. Sensory Compulsions: • Feeling the need to smell your hand after touching areas like your ear or hair. 6. ADHD-like Symptoms / Additional Observations: • Fidgeting or moving your legs when standing or sitting.

Does anyone have hit and run ocd ? Or possibly causing an accident by crossing the middle line and a vechile going into a ditch ?
