Self-reported sexual behaviour is especially sensitive to wording, memory and social expectations. Read these numbers as snapshots of particular surveys, not universal truths.
- One survey found that 43% of women viewed a partner’s fantasies about someone else as a form of betrayal. Couples define boundaries differently; discussing them is more useful than assuming.
- Some studies report lower condom use among sexually active adults over 40. Risk does not disappear with age, and barrier protection and testing remain relevant with new or multiple partners.
- Around 48% of women in some surveys say they have faked an orgasm at least once. The result varies, but it points to the value of communication without performance pressure.
- One age-based survey reported masturbation among 84% of men aged 25-29 and about 60% at age 70, with lower reported rates among women. Such answers are shaped by culture, privacy and question wording.
- A typical ejaculate is often described as roughly 2-5 ml and may contain tens or hundreds of millions of sperm cells. Volume and concentration vary, and fertility cannot be judged by appearance.
- Estimates of 500-1,000 annual deaths linked to autoerotic risk-taking are widely repeated but uncertain. Restricting breathing or using dangerous restraints can be fatal and should never be treated as safe experimentation.
- A survey claim that 21% of men had viewed pornography at work reflects one sample and period. Workplace rules, privacy, consent and digital security still apply.
- One survey reported that 18% of women aged 25-34 believed their sexual peak had passed. Sexual wellbeing does not follow a fixed age timetable.
- Spain, Brazil and Italy have appeared near the top of some international self-report surveys of sexual frequency. Cross-country rankings are highly sensitive to recruitment and cultural reporting.
- An older estimate suggested about 10% of sexually active adults used sex toys. Current use may be different as access, language and social attitudes change.
