One new idea

You can make a habit of each suggesting one thing new to incorporate next time, inspired by what you just did. Like “Next time, what if we try vibrating plug during that roleplay?” or “We did four impact strokes, maybe next time we try doing ten and see if that’s too much or just right.” Continual minor experimentation keeps things evolving. Of course, also feel free to say “Actually I’d be happy even repeating exactly this, it was that good.”
