How long does sex actually last?
According to the landmark Waldinger stopwatch study (2005) where 500 couples timed intercourse with a literal stopwatch, the median duration is 5.4 minutes. A survey of sex therapists defined "desirable" as 7–13 minutes — much shorter than most people assume.
Clinical data on intercourse duration (Waldinger et al.)
- Too short: 1–2 minutes (therapists' consensus)
- Adequate: 3–7 minutes
- Desirable: 7–13 minutes
- Too long: 13+ minutes (associated with discomfort)
Why porn distorts expectations
- Average porn scene lasts 20–40 minutes — 4-7x longer than real sex
- Self-reported duration averages 12+ minutes — nearly double the actual stopwatch data
- Most of a satisfying sexual encounter is foreplay, not intercourse
- Duration does not correlate with female satisfaction — arousal and foreplay do
