That evidence is not just anecdotal but solidly statistical. Yet there is evidence that ladies are looking at erotica created for gay guys in unexpected numbers. While males enjoying lesbian action is a commonplace, its counterpart-women enjoying gay men's pornography-is not as widely recognized. Scenes that are female-only remove any possibility that the viewer could get turned on by another man. Another probable reason for the popularity of lesbianism in hetero men's material is somewhat more troubling: many straight men harbor homophobic feelings or insecurities about their own sexuality such that scenes involving another man can be off-putting or threatening.
Straight men enjoy looking at women's bodies, and lesbian action means more women to gaze upon. 'More female flesh,' is how a man I once knew succinctly put it. It is not difficult to understand why so many heterosexual men enjoy lesbian lovemaking. Mainstream porn films traditionally feature at least one scene of two ladies getting it on. Anyone who picks up Playboy, Penthouse, Hustler, or any hetero men's sex magazine is apt to find pages of female-on-female action. That heterosexual MEN relish watching lesbian sex is a matter of common knowledge as well as social research.
