Assessing differences in physiologic subjective response toward male and female orientated sexually explicit videos in heterosexual individuals
The goal of the present study was to examine sexual response to male and female oriented sexually explicit films in heterosexual men and women. Forty participants (20 men and 20 women; mean age 29.42 years) attended three separate lab sessions. One 15 minute sexually explicit video was shown per session. For session one, all participants viewed a female oriented film selected by the experimenters. The films used for subsequent sessions were counterbalanced male oriented or female oriented clips that had been previously studied. A thermographic camera measured temperature on the penile shaft for men and labia for women. Continuous and discrete self reported sexual arousal was also obtained. Genital temperature was averaged into 15 one minute bins and a repeated measures ANOVA was conducted. Men demonstrated significantly greater increases in temperature over time than women, F (14, 980) 19.27, p .000, however there were no significant differences between films or sex x film interaction. Women reported significantly higher subjective sexual arousal to the films than men, F(1, 69) range 3.89 to 9.67, p range .01 to .05, but there were no significant differences between films or a sex x film interaction. Results suggest that film orientation has minimal impact on physiologic sexual responsiveness in men or women. Although both sexes demonstrated significant increases in sexual arousal for these pre selected films, future laboratory research would benefit from examining whether participant selected stimuli produces a greater response than experimenter selected films.
