Women's genital responses are sensitive to the presence and intensity of sexual cues, yet some stimulus features (e.g., male vs. female actors, consensual vs. non-consensual interactions) have little influence on the magnitude of response—a phenomenon called low cue-specificity. Genital responses are typically assessed using vaginal photoplethysmography, a measure of vaginal vasocongestion, itself a precursor to lubrication. One explanation for low cue-specificity is the preparation hypothesis: Women genitally respond to almost all sexual cues because lubrication functions to protect genital organs from potential injury should vaginal penetration occur. In order to test the preparation hypothesis, both vaginal vasocongestion and introital lubrication were assessed in a sample of 20 women in response to sexually explicit films. While patterns of vasocongestion were consistent with low cue-specificity for gender cues and type of sexual activity, lubrication was specific to women's most preferred sexual stimulus categories. These results are inconsistent with the preparation hypothesis.
