Science research concluded that both men and women get the hormone rush in sex that creates feeling of bonding, but males don't carry that rush beyond the sexual act itself. Males are often diagnosed, as having have sealed off sex, where there is no bonding mentally - purely physical. The male oxytosin rush is gone immediately, in all men. They say this biological response apparently fuels many men's need for very regular sex to feel bonded. Women are wired to bond due to sustained oxytosin after sex and they build on it further with the mind (yes, women can have sealed-off sex, but it's atypical) I mention this because sex with a loose cannon can be dangerous or helpful....depends on how you play.
The reason for this is because of Vasopressin in men and the fact that women have 10 times the amount of Oxytocin baseline than men do. Where the Oxy in a woman rises immediately after sex / orgasm, in men, vasopressin takes over and actually causes the need for separateness! Men do get a huge rush of Oxy at the exact moment of orgasm, but vassopressin takes over very quickly. Oxy synergizes with estrogen in women; vaso synergizes with testosterone in men!
Here is a link and the explanations:
http://www.darionardi.com/BulletinArt9.htmlVasopressin - Vasopressin is made in the brain. Both men and women make it. However, the male hormone testosterone synergizes with vasopressin – the two greatly enhance each other. A woman and man might have equal levels of vasopressin but the man experiences stronger effects. Physically, vasopressin causes water retention and high blood pressure; high levels may increase forehead size. Personality wise, vasopressin influences male social and sexual behavior, public communication, and paternal behavior. In animals (mammals), it
promotes aggression, territorial competition and dominance with other males. It bonds males to mates and children. For men, it also promotes partner recognition, sexual arousal, courtship behavior, monogamy, pair bonding and mate guarding. Vasopressin also improves cognitive ability by enhancing memory.
It allows one to feel separate, with dampened emotional responses and more “sensible” or “reasonable” behavior. Depressed people also have higher vasopressin.
Vasotocin is a variation of vasopressin found in fish, birds and frogs. It promotes vocalization, singing, mating calls and territorial behavior. It causes male animals to respond to the sight of attractive females.
It is found in the human visual system (pineal gland), and male human bonding tends to be more visual. This might explain why adolescent boys of all types are often preoccupied with images of beautiful potential mates!Oxytocin Oxytocin is made in the brain. Both women and men make it. However, the female hormone estrogen synergizes with oxytocin – the two greatly enhance each other. A man and women might have equal levels of oxytocin but the woman experiences stronger effects. Physically, oxytocin facilitates childbirth and nursing for women.
In both sexes, it increases by five-fold during sex. In men, however, it immediately drops and vasopressin rises sharply right afterward - explaining why men generally feel a sudden sense of separateness! Personality wise, oxytocin promotes touching, affection and bonding. In both men and women it rises instantly with a single touch. Oxytocin also influences female social behavior. It promotes “nesting“; monogamy and pair bonding; the nurturing, acceptance and protection of offspring; and pup-retrieval in animals. It influences mate selection. Many of these effects are confirmed in humans as well as animals. For all its positive benefits, high oxytocin inhibits cognitive ability by impairing learning and memory. It encourages emotional extremes but it also prevents depression.
