Introduction: This study is based on the hypothesis that, in men, the initial sexual response to erotic stimuli is triggered by a psycho-sensory pelvic reflex, mediated by the contraction of the pelvic floor muscles (PFM), rather than by an erection.
Objective: The objective is to determine, using a questionnaire that evokes an erotic image, whether there is a correlation between an erotic psycho-sensory stimulus and PFM contraction in men and females and whether this contraction encourages the subject to seek sexual activity.
Materials and methods: An online questionnaire was administered to 270 respondents (134 males, 136 females; mean age = 36.53, SD = 10.7; range 19-63). The questionnaire assessed the relationship between the perception of anterior PFM contraction and an evocative erotic image.
Results: The results show that following an evoked erotic stimulus, there is a significantly higher prevalence of perceived genital sexual responses in males compared to females through PFM contraction. A statistically significant difference was also observed in the desire to engage in sexual activity when perceiving PFM contraction (mean: Males 2.04 ± 0.95 vs. Females 1.02 ± 0.88; p < 0.001).
Conclusions: In this sample, an evocative erotic image triggers the perception of the genital sexual response via PFM contraction in more males than females. Additionally, PFM contraction, when perceived, prompts more males to seek sexual activity. These findings support the hypothesis that Pelvic Floor Muscles contraction is the initial response to psycho-sensory stimulation in men and a trigger for male sexual behaviour.
