Abstract
Orgasm is a phase of the human sexual response, and the possible discrepancies between male and female ways to experience it are still not clear in the literature. There is a lack of tools to adequately assess orgasm perception. This study aims to develop an instrument and verify possible differences between males and females. We constructed the Orgasmic Perception Questionnaire (OPQ) through different stages: first, 316 items selection was conducted on a sample of 96 people, where items came mainly from written descriptions of orgasm perception; second, an exploratory factor analysis was conducted on 674 Italian adults with a 63-item OPQ; finally, a confirmatory factor analysis was conducted on 1100 Italian adults with a 47-item OPQ. In the first study, 63 items fitted an equidistributional pattern and were to form the 63-item OPQ used for EFA. The EFA showed that five factors out of 47 explained 44.01% of the total variance and were named: Ecstasy, Contractions, Relaxation, Power, and Sensations. The confirmatory factor analyses run on the 47-item OPQ confirmed that the five-factor structure fits. Moreover, females scored higher than males with an adequate effect size in two factors: Contractions and Sensations. In conclusion, the OPQ could be a useful tool in both clinical settings and research studies to investigate the perception of orgasmic experience in its totality.
