What is the least common sexual act with men
Executive summary
There is no single, definitive answer in the provided reporting for “the least common sexual act with men”; surveys and academic studies instead report which acts are most and most‑commonly reported and emphasise wide underreporting and variation by population and question wording (notably: kissing, oral sex and partnered masturbation are commonly reported while rarer acts get sparse measurement) [1] [2] [3]. Available sources do not list a ranked, population‑representative ordering that identifies one least‑common act across all men or all contexts (not found in current reporting).
1. Survey headline: common acts are measured, not “the least common”
Large public surveys and sexual behaviour reviews focus on prevalence of several common acts — for example, Wikipedia’s synthesis of studies reports kissing on the mouth (74.5%), oral sex (72.7%) and partnered masturbation (68.4%) as among the most commonly reported behaviours between men, implying less‑frequent acts exist but without producing a universal “bottom” item that would answer your question directly [1]. Health reporting likewise lists vaginal intercourse (in heterosexual samples), oral sex and partnered masturbation as commonly measured activities, underscoring that the literature concentrates on frequent acts rather than exhaustively ranking rare ones [2].
2. Academic work: some acts are specifically studied because of health implications
When researchers study sexual acts among men who have sex with men (MSM) they often concentrate on acts with clear clinical relevance — receptive anal sex, oral sex, manual sex and sequential combinations — rather than trying to establish which activity is the rarest overall. For instance, an Archives of Sexual Behavior study recruited participants who denied receptive anal sex in the past two years to understand sequence and infection risk, showing research priorities are driven by disease transmission questions rather than by mapping a comprehensive frequency hierarchy of all sexual acts [3].
3. Underreporting and question framing distort apparent rarity
Multiple sources warn that sex between men is significantly underreported in surveys and that results vary greatly by how questions are asked, sample composition and stigma in respondents’ environments [1]. That means an act reported as “rare” in one survey may simply be under‑measured in that study; social desirability, criminalisation or survey design can push some behaviours out of sight, so “least common” labels risk reflecting measurement bias rather than true population frequency [1] [3].
4. Context matters: age, relationship status and population change prevalence
General sexual frequency and the mix of acts change with age, relationship status and social trends. Multiple analyses point to falling overall sexual frequency among younger cohorts and higher sexual inactivity in certain groups, which shifts the denominator for any behaviour-based ranking [4] [5]. A behaviour that looks rare in a sample of older or more sex‑inhibited respondents might be more common among younger, openly gay or sexually adventurous groups — the sources stress heterogeneity rather than a single national “least common” act [4] [5].
5. Specific acts often cited as “less common” — but evidence is fragmented
Some activities (for example, frot/frottage—penis‑to‑penis rubbing—or certain kink practices) are described as distinct but not ubiquitously measured; Wikipedia mentions frot among practices between men but does not provide a population‑level frequency placing it at the bottom [1]. The Archives study and other sexual health datasets document particular acts when relevant to infection risk, but these do not equate to representative prevalence rankings that would let us confidently name a single least‑common act [3] [1].
6. How to get a clearer answer: targeted, representative measurement
To identify a true “least common” sexual act among men you would need a recent, large, population‑representative survey that (a) lists an exhaustive set of acts, (b) uses neutral wording and privacy‑protecting methods to reduce underreporting, and (c) stratifies by age, sexual orientation and relationship status. None of the provided sources supply that comprehensive ranking; instead they provide pieces (prevalence of common acts, warnings about underreporting, targeted clinical research) that explain why the simple question is harder to answer than it seems [2] [1] [3].
7. Bottom line for readers
Available reporting shows which male‑to‑male acts are commonly measured and emphasises measurement limits; it does not produce a reliable, single “least common” sexual act across all men (not found in current reporting). Any claim that a particular act is the least common should be treated cautiously unless backed by a recent, representative survey explicitly designed to answer that comparative question [1] [3].
