There were quite a lot of sadistic fantasies in my head up to that point, but most of them I found haunting instead of pleasuring. My enjoyment of submissiveness and somewhat the masochism started off the same way.
I'd need more experience to really embrace it, and even then... Sadism is a rougher path to get away with. Masochism has the liability risks connected to my partner, which gives me far less room to worry.
