did something trigger your OCD or did it just develop randomly?

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.

So maybe the title wasn't the best to to put it but when you guys start having obsessive thoughts how do you stop them before it turns into compulsions and anxiety?

I started dealing with OCD when I became fixated on health issues, particularly the fear of contracting a life-threatening disease. If I experienced any kind of medical symptom, no matter how small, that even remotely hinted at something potentially fatal, it would drive me crazy, and I couldn’t stop obsessing over it. Then one day, I started having intrusive thoughts about accidentally hitting someone with my car, and I would end up driving in circles to check if I had. Eventually, I found myself overwhelmed by a flood of new obsessive thoughts and compulsions. One day, while I was at the park, a squirrel came near me, and for some reason, I felt like it attacked me. I Googled it and learned that squirrels could carry rabies, which spiraled me into a deep fear of rabies. I became consumed with the thought I received a bite from a squirrel, raccoon, or bat any time I’m in areas that trigger me. It started off only being inside then transferred to even being in my own home. This made me obsess over every physical sensation in my body, compulsively checking to make sure nothing was wrong. One compulsion that I hated the most would to be putting rubbing alcohol on me to make sure that I had no open wounds. Every day feels like I’m walking around in a fog of anxiety, constantly worrying that I won’t even make it to old age. Sometimes, it gets so overwhelming that I just want it all to end. It stresses me so bad at times to where my brain feels like I’ve been studying all day.
