What futuristic movie had people having sex in machines?

There was this older sci-fi futuristic movie I saw in high school in
1983, so the movie was from the 70's (or older). It had these sex
machine booths where 2 people went and the machine "did all the work."
It also showed women walking around with these phone-like dials on
their hips, with intercom messages for them to dial up their birth
control. What movie was that?
