To better understand the impact of sexual stimuli on genital pain, a new instrument was developed: the Vaginal Pressure Inducer (VPI). We administered gradually increasing vaginal pressure with the VPI to sexually functional women while watching a neutral, erotic or explicit sex film. Women had higher unpleasantness thresholds in a sexual context compared to a non-sexual context. Moreover, ratings of pleasurableness were higher in the sexual compared to neutral context and most so during the explicit sexual film. These results provide initial support for the suitability of the VPI to study determinants of pleasant and unpleasant appraisal of vaginal pressure.
