As the title suggests, I cannot stress that changing things up no matter how little may give you great results. Example: For my last couple Aneros-less sessions, instead of teasing both my nipples, since my right arms been hurting, I teased just my left one.
I cannot tell you what a positive difference this has made! I may have been overstimulated with both, as before I was rudely interrupted with a work phone call (always silence your phone haha) I had 3 dry orgasms that all felt great.
So yeah TL;DR: Experiment with different things no matter how little the change.
