Depraved! (1967)

A swinger's tour of the far-out, unnatural and forbidden ways to love!

Vera is a bisexual who learns that she's pregnant but does not know who the father is and finds solace with a lesbian friend. Linda cheats on Rod with his brother-in-law, while Polly is a lesbian in denial whom attends transvestite parties to escape from being around her misogynistic husband Bob.
