After Sex (2000)

Five 1990s Californian couples, wed but one, illustrate or contradict the sexual relationship theories of two TV talk show hosts. The women shamelessly presume all men, including theirs, to be unfaithful, yet embank on a girls-only trip to LA, which turns orgiastic to the point of adultery. Back home, loyalty and other complications arise, whether to tell the cuckolded partners or protect one's own buddies.
