==Laboratory comparison of homosexual male versus homosexual female sex==
Masters and Johnson randomly assigned two men into couples and two women into couples and then observed them having sex in the laboratory, at the Masters and Johnson Institute. They provided their observations in ''Homosexuality in Perspective:''

{{blockquote|Assigned male homosexual study subjects A, B, and C..., interacting in the laboratory with previously unknown male partners, did discuss procedural matters with these partners, but quite briefly. Usually, the discussion consisted of just a question or a suggestion, but often it was limited to nonverbal communicative expressions such as eye contact or hand movement, any of which usually proved sufficient to establish the protocol of partner interaction. No coaching or suggestions were made by the research team.|p. 55}}

According to Masters and Johnson, this pattern differed in the female homosexual couples:

{{blockquote|While initial stimulative activity tended to be on a mutual basis, in short order control of the specific sexual experience usually was assumed by one partner. The assumption of control was established without verbal communication and frequently with no obvious nonverbal direction, although on one occasion discussion as to procedural strategy continued even as the couple was interacting physically.|p. 55}}
