I’ve never planned a scene, should I?

My sub and I never plan scenes, they just happen. We do talk a lot about kinks, fantasies, limits etc but everything we do (even cnc scenarios) are done organically so to speak. There really never has been any issues arising from this.

I get confused cause everyone here is talking about planning scenes beforehand but I’ve never really understood that. Am I weird? Are we missing out on something?
