The Circuit is a type of sexual escort service that appears in the film Logan's Run that teleports prostitutes into the room of the caller.
Logan 5 views two options before selecting Jessica 6 but she is uninterested in his advances.
The premise of having the circuit in the film might be suggestive of LGBT progressiveness as Logan suggests Jessica could be a lesbian who likes other women as for why she isn't interested in him and he theoretically could have picked the first option which was a male.
