Genital lubrication: A cue-specific sexual response?

Area of Science:

• Psychology
• Human Sexuality
• Physiology

Background:

• Women's genital responses show low cue-specificity, meaning they react similarly to various sexual stimuli.
• The preparation hypothesis suggests this is to protect against potential injury during intercourse.
• Vaginal vasocongestion and lubrication are key genital responses studied.

Purpose of the Study:

• To test the preparation hypothesis regarding women's genital responses.
• To investigate if lubrication is cue-specific, unlike vasocongestion.
• To examine the relationship between sexual cue features and genital responses.

Main Methods:

• Assessed vaginal vasocongestion and introital lubrication in 20 women.
• Used sexually explicit films as stimuli.
• Measured genital responses using vaginal photoplethysmography.

Main Results:

• Vaginal vasocongestion exhibited low cue-specificity for gender and interaction type.
• Introital lubrication, however, was specific to preferred sexual stimulus categories.
• These findings contradict the preparation hypothesis's predictions.

Conclusions:

• The preparation hypothesis does not fully explain women's genital responses.
• Lubrication specificity suggests a more nuanced role beyond simple preparation.
• Further research is needed to understand the determinants of women's sexual arousal patterns.
