The Science of Better Orgasms: What 500,000 Data Points Reveal | Anna Lee | Episode 34
"Knowledge is pleasure." — Anna Lee
What if the best lessons about orgasms, arousal, and sexual health came from data and engineering?
Not from guesswork. Not from myths. From a mechanical engineer whose work helped build one of the world's largest physiological datasets on female sexual response.
Anna Lee went looking for those exact insights. What she discovered challenged common assumptions about sexual pleasure, body literacy, and the massive research gap surrounding female sexual function.
In this episode of The Sexology Lab, Anna sits down with the host to discuss the technology behind the Lioness biofeedback vibrator, why so many people look for a "magic pill" for better orgasms, and how tracking pelvic floor contractions can help people better understand their bodies.
But the conversation doesn't stop with data. It expands into the systemic challenges of launching a business in the taboo sex tech industry, navigating censorship and investor biases, breaking Asian-American cultural stigmas around sex, and exploring how AI might shape the future of sexual wellness.
What This Episode Explores
"If my mom could do it, anybody can do it. It's just having vulnerable, open conversations and taking that first dive into being able to have intimate conversations." — Anna Lee
Pleasure isn't just a physical feeling; it's an opportunity for self-awareness and body literacy. This conversation explores how biofeedback and data can transform how we approach sexual health, personal relationships, and female sexual response.
Anna and Michelle discuss:
What pelvic floor contractions reveal about involuntary arousal and orgasm patterns.
Why female sexual health research has historically been underfunded and understudied.
The surprising findings gathered from over 500,000 orgasm sessions.
How factors like stress, caffeine, alcohol, THC, and edging impact orgasm quality.
How tracking sexual response builds confidence, self-advocacy, and better communication with partners.
The realities of banking discrimination, ad bans, and censorship facing sex tech entrepreneurs.
How machine learning and pattern recognition can personalize sexual wellness while safeguarding user privacy.
Breaking cultural taboos as an Asian-American leader in the sexual wellness space.
Meet anna lee
Anna Lee is a mechanical engineer, co-founder, and CEO of Lioness, a sexual wellness startup that built the world's first biofeedback vibrator designed to track arousal and orgasm patterns via pelvic floor contractions.
Growing up in Korea in a religious, conservative family, sex was never discussed openly. After studying mechanical engineering and working at Amazon, Anna realized that consumer products—including sex toys—were rarely designed with women's bodies or data-driven engineering in mind.
Her work with Lioness has been featured in Forbes, Newsweek, and numerous tech and health publications, recognizing her as a pioneer advancing women's healthcare and sexual pleasure through engineering.
Anna also collaborates with medical researchers, pelvic floor physical therapists, and academic institutions to expand scientific knowledge surrounding female sexual function.
3 Key Takeaways
1. Knowledge Is Pleasure
There is no "magic pill" for better orgasms. The most reliable path to better sexual experiences is building body literacy and curiosity. Taking time to understand your unique physiological responses, combined with accessible techniques like edging or clitoral warm-ups, creates far more meaningful improvements than searching for a quick fix.
2.Orgasm Data Fills a Massive Scientific Gap
Female sexual response has historically been neglected in medical research due to small sample sizes and the logistical challenges of lab testing. By measuring involuntary pelvic floor contractions during orgasm through a direct-to-consumer device, data-driven sex tech can map physiological patterns across hundreds of thousands of sessions. Over time, tracking orgasmic changes may even serve as a "canary in the coal mine" for broader physical or neurological health changes.
3. Direct Language Overcomes Stigma
Building a business in the sex tech space presents unique hurdles, including financial discrimination, payment processor bans, trade show censorship, and investor awkwardness. Overcoming these taboos requires ditching euphemisms and speaking openly, comfortably, and directly about bodies, clitorises, and orgasms.
Who This Episode Is For
This conversation is especially relevant for individuals interested in body literacy, biofeedback, and understanding the physiological factors that influence sexual pleasure.
It is also valuable for entrepreneurs navigating stigmatized industries, individuals working in sex tech, and anyone curious about how data and AI can support personal health.
Sexologists, sex therapists, pelvic floor physical therapists, and health educators will find useful perspectives on pelvic floor function, research methodologies, and how tracking arousal data can empower clients to communicate their needs to partners.

Quick Answer: What Can Data Teach Us About Orgasms?
Physiological data can teach us how internal and external factors directly affect arousal and orgasm quality. By measuring involuntary pelvic floor contractions, tools like the Lioness biofeedback vibrator show how duration, intensity, and timing shift based on variables like stress, fatigue, substances (caffeine, alcohol, THC), and techniques like edging or foreplay.
Ultimately, data validates personal experiences, removes shame, and helps individuals recognize their unique patterns rather than comparing themselves to universal myths.
Expanded Insights From the Conversation
How Biofeedback Tracks Sexual Response
When Anna Lee and her team designed Lioness, they set out to find a reliable physiological indicator for orgasms that could be measured outside a clinical laboratory setting. While brain scans (fMRIs), heart rate, and skin perspiration reflect arousal, involuntary pelvic floor contractions offer a direct measurement of orgasm across all body types.
By embedding sensors into a vibrator, the device captures rhythmic squeeze-and-release patterns without requiring invasive machinery or lab visits. Users can view their session graphs through a mobile app, allowing them to see their arousal curve and orgasm duration in real-time data.
Surprising Trends From 500,000+ Orgasm Sessions
Aggregating anonymized data from hundreds of thousands of sessions revealed several unexpected patterns:
Average Orgasm Duration: Lioness data showed that the average female orgasm lasts 28 seconds, aligning closely with clinical literature.
Popular Days for Self-Pleasure: Sundays consistently rank as the most popular day of the week for masturbation.
The Groundhog's Day Effect: For consecutive years, Groundhog's Day unexpectedly ranked among the top three holiday periods for self-pleasure sessions, alongside Valentine's Day.
Testing the "Sex Experiments"
Through monthly "sex experiments," Lioness users test specific variables against their personal baselines:
Edging & Mutual Masturbation: Consistently produced the longest and strongest orgasms in user data.
THC Lube: Showed significant increases in orgasmic intensity for users where it is legally accessible.
Caffeine vs. Alcohol: Caffeine tended to decrease the time required to reach orgasm, whereas alcohol consistently decreased overall orgasm quality.
Stress: High stress levels markedly reduced orgasmic strength and frequency.
Overcoming Taboo in the Sex Tech Industry
Launching a sexual wellness hardware startup required overcoming barriers that traditional tech companies rarely face. Financial institutions frequently denied bank accounts, social media networks banned advertisements, and major technology trade shows like CES historically prohibited sex tech displays.
Anna learned that pitch strategies built around overly conservative medical euphemisms often confused investors. By transitioning to direct, comfortable language—using precise terms like clitoris, vibrator, and orgasm—the team screened for aligned investors and normalized conversations about sexual health.
