Pre-session rituals?

So I’ve been working on my technique since my first super-o a few weeks ago, and in preparation for a session tonight I’ve been tensing my prostate on and off all day.

Anyway, this got me thinking about what other people might do ahead of sessions. Obv there’s the obvious/the things in the Wiki (cleaning, relaxing, being aroused etc.) but do others have other rituals or go-to prep activities?

This isn’t a help-me-with-my-technique type of post, it was just something that occurred to me and in curious. And this sub/community has always been welcoming of questions and forthcoming with comments, so figured I’d ask.
