Before I outed myself at the Lodge, I found myself noting something unexpected....
Many of the guys routinely walked, sat, etc. in ways that are stereotypically feminine, although nothing appeared effeminate when they did it.
In a couple of months' observations, I saw some perfectly crossed legs, for example.
I've spent four decades swimming, bicycling, walking, even ballet (years ago), a bit of yoga & uncountable hours of zazen. And I can't sit in a classically feminine manner at all IMO. (Doesn't stop me from giving it a go, of course.)
