Fingering during session?

Anybody else run their fingers around the aneros in mid session? It’s almost like being rimmed, it made for a unique feeling but not sure if it distracts from letting the helix do it’s thing.

I’ve had some pretty intense sessions, lots of involuntary shaking and head to toe buzzing, feels like it builds until I hit a ceiling but I have trouble finding time to go much beyond 90 minutes for a session.
