“Women have less direct relationship to anger...When a woman "bites" her tongue to avoid expressing anger, its not at all socialization. A lot of it is brain circuitry. Even if a woman wanted to express her anger right away, often her brain circuits would attempt to hijack this response, to reflect on it first out of fear and anticipation of retaliation. Also, the female brain has a tremendous aversion to conflict, which is set up by fear of angering the other person and losing the relationship. Instead of triggering a quick action response in the brain, as it does in males, anger in girls and women moves through the brain's gut feeling, conflict-pain anticipation, and verbal circuits.
Scientists speculate that though a woman is slower to act out of anger, once her faster verbal circuits get going, they can cause her to unleash a barrage of angry words that a man cant match.
Typical men speak fewer words and have less verbal fluency than women, so they may be handicapped in angry exchanges with women.
Often when I see a couple who are not communicating well, the problem I see is that the man's brain's circuits push him frequently and quickly to an angry, aggressive reaction, and the woman feels frightened and shuts down.”

“During times of physical separation, when touching and caressing is impossible, a deep, longing, almost a hunger, for the beloved can set in. We are used to thinking of this longing as only psychological, but it's actually physical. The brain is virtually in a drug-withdrawal state. During a separation, motivation for reunion can reach a fever pitch in the brain. Activities such as caressing, kissing, gazing, hugging, and orgasm can replenish the chemical bond of love and trust in the brain. The oxytocin-dopamine rush once again suppresses anxiety and skepticism and reinforces the love circuits in the brain. From an experiment we also know that oxytocin is naturally released in the brain after a twenty-second hug from a partner- sealing the bond between huggers and triggering the brain's trust circuits.”
