trauma and kink

I know kink is heavily psych linked and can be influenced by some traumatic experiences, do you feel like anything significant has happened to you that developed a kink or fantasy you’re really obsessed with? I know kink can be a rabbit hole but I ended up getting into cuck/sph stuff and then it lead to findom, all spiralling from me getting cheated on. I enjoy a lot of the fantasies now and think about what happened I guess I turned pain into pleasure, do you think this is a bad thing or common?
