Neurochemical “Big Three” (dopamine / oxytocin-vasopressin / endogenous opioids)
A shorthand for three neurochemical systems often linked to sexual motivation and reward (dopamine), bonding and attachment (oxytocin/vasopressin), and pleasure/comfort (endogenous opioids).
What This Really Means
These systems interact: novelty can boost dopamine, closeness can strengthen bonding signals, and soothing touch can support comfort and satisfaction.
Popular media can exaggerate simple “chemical” explanations, so it’s best used as a lens rather than a diagnosis.
Culture and relationship meaning strongly shape how these reward signals are experienced and interpreted.
Examples
Anticipation and flirting increasing motivation and excitement
Cuddling and affectionate reassurance deepening a sense of bonding
Feeling calm, satisfied, and connected after pleasurable intimacy.
