Helen Fisher at Oprah.com explains how even though men and women have evolved to define intimacy in different ways, a blast of oxytocin in the male or female brain, will bring feelings of both intimacy and trust..
‘And get the oxytocin flowing. Oxytocin is a brain chemical that produces feelings of trust and attachment. Men get a blast of it when they kiss, women feel a rush when they hold a lover’s hand, and during orgasm, both partners are flooded with the powerful substance. So last but not least, enjoy each other physically. Good sex really does build intimacy.’
