Episode notes
Oxytocin As The Bonding Switch
- Oxytocin is the primary biological mechanism for emotional bonding and functions as a multifaceted safety cue.
- Higher oxytocin increases relaxation, trust, generosity, and openness when you're around bonded people.
Women Bond Stronger Through Caregiving Biology
- Average women have about three to four times the circulating oxytocin of men, which makes women generally more bonded in relationships.
- For women the strongest oxytocin trigger is breastfeeding and nipple stimulation as the sexual shadow of that caregiving loop.
Male Bonding Anchored In Orgasm
- Orgasm is the activity that most consistently raises oxytocin in men, linking sexual frequency to increased emotional bonding.
- Repeated sex with a particular woman makes a man more likely to become emotionally attached and less likely to abandon her.
