Exhibitionist

Clinical and lifestyle uses of the word point in opposite directions and the distinction matters. Wikipedia's overview of exhibitionism separates exhibitionistic disorder — the DSM category, which requires that the exposure be directed at a non-consenting person — from the much broader and largely unproblematic interest in being watched during sex by people who have agreed to watch. The American Psychiatric Association draws the same line in its DSM-5 paraphilias framework: an atypical sexual interest only becomes a disorder when it causes distress, impairment, or involves a non-consenting party.

Lifestyle exhibitionism operates entirely inside the consensual frame. The audience has opted in, the venue or party has set explicit norms about where and how people can watch, and the exhibitionist's pleasure comes from the agreed-upon visibility rather than from surprise or violation. It pairs naturally with voyeurism — its mirror — and most lifestyle environments treat the two as complementary rather than separate scenes, with same-room play, open-door bedrooms, and group play areas designed to make the dynamic comfortable for both sides.

Survey research summarised in the same Wikipedia article reports that interest in voyeurism, sadomasochism, and couple exhibitionism is statistically common rather than rare in the adult population, which tracks with how routinely lifestyle clubs and resorts build their layouts around it. The legal distinction is the constant: any exposure outside the agreed venue and audience falls back into the indecent-exposure category and is treated as a crime, regardless of intent.
