Send us Fan MailAnna Lee, CEO and co-founder of Lioness, joins Judith to reveal what a dataset of around 100,000 orgasms has uncovered about female sexual pleasure — and how little the science had actually established before. This part covers how the Lioness biofeedback vibrator measures involuntary pelvic-floor contractions, the three distinct orgasm patterns the data reveals, and the finding that will genuinely surprise most listeners: orgasm strength tends to increase as women move into their fifties and sixties, not decline.Key topics discussed- What the Lioness device actually measures, and how biofeedback orgasm data works- The three orgasm patterns — ocean wave (rhythmic, most common), avalanche (high force tapering down), and volcano (rare, single explosive peak) — identified through involuntary pelvic-floor contractions- Why those patterns matter: correcting four decades of incomplete research based on a 1982 study of only 11 women- The type-switching debate: whether a person moves between orgasm patterns over time, and what the current data does and does not show- The age finding: women aged 51–60 appear to reach orgasm fastest and generate the strongest peak force — contradicting the widespread assumption that sexual pleasure declines with age- Why this podcast cares: the knowledge gap in female sexual health, and how understanding your own body is a health act, not a vanity oneTimestampsThese are estimates and may shift in final editing.0:00 — Introduction: Judith introduces Anna Lee and Lioness1:00 — What Lioness measures: involuntary pelvic-floor contractions during pleasure and orgasm2:30 — How the app works: pairing the device, reading the data, tracking lifestyle factors4:00 — The three orgasm patterns: ocean wave, avalanche, volcano6:30 — The 1982 Bohlen study (n=11) versus the Lioness dataset (~100,000 data points); the Pfaus/Hartmann research8:30 — The type-switching debate: do people move between patterns?10:00 — The age study: orgasm strength increases in the 51–60 range12:30 — Why this matters: "knowledge is pleasure," and the parallel to tracking sleep and nutrition14:00 — Fertility and orgasm type: what we do and do not know15:30 — End of Part 1ReferencesLioness Smart VibratorThe biofeedback device discussed throughout.
