I just get to things decades late lol
I think I have something similar but not quite the same, for me I think a lot of it is that it feels like there's a lot of emotional potential in engaging with something everyone already has big feelings about. What if I have big feelings about it and then I have big feelings? What if I don't, and then I'm just on the outside??
And I just find all that possibility a bit aversive so I just wait until everything dies down and then go try it after dragging my feet for 15 years :)
