Does anyone know when their obsessions first started?

Last year during April I started to experience groinal responses when I looked at kids. I was terrified of what it could mean and decided to attempt two weeks later. The very next day I had those responses I decided to attempt. I didn’t really have the courage to do so at that time but I started experiencing images about disturbing things done to kids and as days went by it got worse. April 16 was the last straw and I couldn’t take it anymore. I ended up in a mental hospital but before I ended up there I had searched up what I was experiencing. That’s when I started to understand that it was OCD. I felt relieved for a few moments until I felt the urge to get more information. I saw lots and lots of things and many comments saying that it wasn’t normal and that people who went through this were disgusting people who shouldn’t be allowed to roam free. That’s when my anxiety and fear became worse and I tried to get rid of it but nothing worked. I shook the entire time I was awake, I didn’t have motivation for anything anymore, I just felt so disgusting. In the end, I’m so glad I ended up in that mental hospital or else I wouldn’t be here with my friends and family. Thank you for reading my story, I’m so glad that I’m not alone

So basically I didn’t know till my hocd started. But looking back at my life I had ocd since I was a kid. Like 6-7 years old. First time happening I remember that when I was doing stuff many times I had to say something like a little poem in my head to stop it. Then I had this thing were if I felt my left foot touch the floor 5 times I had to do the touch the floor with my right foot too. Then I had something I guess contamination??? Basically after washing my hands I had a sensation on my hand like I could still “feel” the germs and I had to wash them again. Then I started having thoughts of my family members getting hurt. I had intrusive thoughts about me hurting my dog. Then I had this obsession that a guy who used to be in my school is looking for me to beat me up. And how it’s this obsession about my sexuality even tho I never doubted or questioned it before. Is that possible??? Like can you be born with it? I’m pretty sure both my parents have it too. At least at some level. Take my father for example he had an obsession that he was going to die the moment he turned 30.

For me it was a weird intrusive thought and after that I slowly started developing anxiety and I felt a weird thing like I was losing my attraction to girls. Then I woke up one day in complete panic cuz it felt like I had lost feelings for girls suddenly and I started searching online how to know if you’re gay if sexuality changes suddenly and I took some gay tests or sexuality tests online. Chat gpt was a big thing back then too. That was before therapy and before I knew what ocd is.Can anyone relate?
