371 – Women’s sexual health: desire, arousal, and orgasms, navigating perimenopause, and more
Peter Attia MD2h 1mNov 3, 2025
Watch the originalTo maintain sexual activity in your 80s–90s, you need a VO2 max of at least 45–50 ml/kg/min now, since sex requires ~7 METs (~25 ml/kg/min VO2), and you need meaningful headroom above your maximum.
Key takeaways
Sex requires ~7 METs; need VO2max of 30+ to sustain it
Sex requires ~7 METs; need VO2max of 30+ to sustain it
- 7 METs ≈ VO2max of 25 mL/kg/min; you need headroom above max effort, so ~30 mL/kg/min minimum.
- To maintain that capacity in your 80s–90s, you need VO2max of 45–50 now — a concrete longevity target.
Only 10% of women orgasm from penetration alone — anatomy explains why
Only 10% of women orgasm from penetration alone — anatomy explains why
- Clitoris-to-vaginal-opening distance <1 inch predicts penetrative orgasm; >1 inch makes it unlikely without external stimulation.
- G-spot orgasm (internal clitoral branch) also ~10%; 90% require external clitoral stimulation regardless of partner or position.
Foreplay >21 min → >90% of women orgasm; vaginal anatomy physically changes
Foreplay >21 min → >90% of women orgasm; vaginal anatomy physically changes
- Vagina expands from ~3.5"×9" and changes angle during arousal — insufficient foreplay causes pain in 30% of women.
- Angle change enables deep-penetration positions that are otherwise painful; foreplay duration is a mechanical prerequisite, not just preference.

“Orgasms beget orgasms. Meaning like the more orgasms you have, the easier it is to have an orgasm in terms of training the system.”
