Strangers When We Mate is a very obscure 1973 California adult flick about a large gathering of people (all strangers to each other) brought together by a hippie loon at a big ranch chic house as an experiment in free lovemaking. All are given a mild aphrodisiac and swap off with each other in any combination that strikes their addled fancy in the home's many groovy rooms. Cast: Becky Sharpe, Mona Leasah, Russell Blue, Carla Crabbe, Connie Lingus, B J Dyke, Hardy Bull, Kenny Dooer, Heywood Hymen, John Holmes, Others
