#But I do feel there’s probably some. Rules of mass displacement transformation or cultural subtext via body language / wing positioning

I think there’s a few options. Here are the most standard IMO:

Personal Space. (The easy, neutral option. Requires a large berth but quite doable.)

Head-on-stomach. (Romanticized in holo-films, Cybertronian media wants you to believe this is how ALL winged mechs share berths. Picture this tooth-rottingly charming scene: You, your partner sharing space, their head in your lap; almost as close to your spark as they can get. Your wings are attractively splayed out to either side, the berth is warm and cozy, their calm and sleepy adoration spills into the air as they smile up at you… HAH! The truth is, due to the high percentage of warframe-spec fliers, this is an exercise in trust and often in futility.)

somehow both directly opposed to and overlapping with #2 there is …SEEKER PILE!!!!! (e.g. the wings are there TO be laid on and if you can’t throw someone off that’s on YOU.)

Am I the only person wondering how one would share a berth with a winged mech without like, laying on their wings? It's not like they're detachable.
