Is Body Dysmorphia Disorder related to OCD or are they completely different disorders?

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.

Why do some people develop OCD?

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.
