The space between two men on a couch, in a car, between urinals
the straight space exists between straight men. Men using urinals must have at least one urinal in between them unless only two urinals are present.

The straight space on a couch or in the back seat of a car requires men sitting on the same couch together to have either a girl in between them or a one cushion space
