Orgasm

This cross-sectional observational study uses an online survey to describe the epidemiology of sexual health, sexual behaviour and sexual function in Spanish-speaking adults, and to estimate the prevalence and phenomenology of expanded (altered) states of consciousness associated with orgasm. The study has two prespecified aims, analysed and reported as two separate manuscripts: 1. sexual health and behaviour epidemiology and associated factors; and 2. expanded states of consciousness associated with orgasm. Recruitment is via social media with complementary channels. Sexual function is assessed with a brief study-developed instrument administered identically to all participants, enabling direct between-sex comparison. Survey weights are applied. Reporting follows STROBE and CHERRIES.
