Starting a scene can often be the most difficult part. The transition from chatty date night to intense BDSM experience seems like a wide chasm to jump! To overcome this, use a “Curtain.”
Ask your partner if they need to use the restroom, or a glass of water. Send them off to it (or go yourself,) while explaining that “when you come back, we’re going to begin.” Let that moment apart be the curtain that allows you to put on your mean face, and them their frightened rabbit act (or however it is they bottom.) That brief breathing space is like the space between tracks on an album. Embrace it.
Good luck, have fun.
Wonderful transition tip!. And if you’re a Daddy a lot of Littles will already start drifting if you say “do you need to get a drink or go potty…” instead.
