The sexploitation drama Whose Child Am I? (1974) stars Kate O'Mara and Paul Freeman as Barbara and Paul Martin, a couple whose inability to conceive a child leads them to try artificial insemination. Meanwhile, a lesbian couple is also trying to have a baby, a blackmailer is trying to extort money from the Martins, and a female doctor is falling for an older man. You’ll be shouting “O’Mama” when you see O’Mara’s mams, muff, and mudflaps as she gets it on with some guy in a hospital.
