Hyperfixations on people

Does anyone else experience obsessive hyperfixations on people in their lives? I’ve seen several times where someone might become fixated on an actor or musician which results in watching/listening to all of their work, finding their social media, etc; and I’ve done this as well. But I sometimes become obsessed with people around me. It usually starts really chill, like making a new friend. But then I spiral and I want to know everything about the person. I want to spend time with them and talk to them constantly. I’ve never stalked anyone or engaged in anything dangerous or outwardly creepy, but the thoughts definitely feel creepy sometimes. There are, most times, sexual dreams involved even if I may not feel like I’m sexually attracted to the person. When I was a kid I interpreted it as having crushes. Thinking about that cute boy in math class all day and imagining our adult life together seemed like a fairly common occurrence amongst my friends.
But after the few times it’s happened as an adult, I’m realizing it’s actually probably part of my OCD. My current obsession is going on three years. I’ve kept it under control for the most part, but it has been growing in intensity the last few months as I’ve had the opportunity to spend some time with this person.
