Sexy time duration (IELT) presets
The 5 minute 20 second pooled median comes from a five-country study, not a worldwide population average. Country values are historical approximations of median intravaginal ejaculation latency (IELT), not total sex duration or a prediction about individuals. Selecting a preset adjusts the duration slider. Moving the slider switches the menu back to Slider controlled (manual).
Research sources
Waldinger et al. (2005) — A multinational population survey of intravaginal ejaculation latency time. Source of the 5.4-minute pooled median and the historical country presets shown above.
Waldinger et al. (2009) — A five-nation survey to assess the distribution of the intravaginal ejaculation latency time among the general male population. Follow-up research reporting a pooled median of approximately 6.0 minutes; its figures are not mixed into the current presets.
These studies measure IELT, not total sex duration or uninterrupted thrusting time. Figures cited here are based on the publicly available study abstracts; the full articles were not reviewed.
