Charlie StrossMad SF speculation:
In 1918 many young men came home from the trenches with a new sexual fetish: gas masks.
Spacesuits are still exotic, but in an SF setting with space travel, they're going to be as common as respirators (and better desined than ours).
What sexual fetishes do future space suits lend themselves to? (Noting that long duration ones *will* require perineal connections to deal with waste ... and possibly other needs.)
