Sex!! Orgasm! Relationship & Monogamy: Science of Orgasm

For men it is quick, easy and ESSENTIAL FOR REPRODUCTION.
For women, it is slow, difficult and PURELY FOR PLEASURE.
Yet despite such differences, it brings the sexes together and is the basis of the monogamy that distinguishes us from other animals

By virtue of a series of devilishly clever evolutionary tricks, or perhaps due to sheer happenstance shaped by cultural factors, women and men have quite different sexual desires, different sexual experiences and different sexual aims. They do not actually need one another to enjoy orgasm. Yet since prehistory, these two very different tribes have continued to seek out one another's company and spend their lives broadly together, centring a large part of their shared existence on an activity - sexual intercourse - of which they have a very different experience.



It is axiomatic that women fall in love first and discover lust later, while men fall in lust and only subsequently learn to love.
Indeed, it is a close-run thing whether the most striking disparity between the male and female yearning for orgasm is emotional or physical.

The orgasmic spasm lasts a few seconds to a minute at the most, but is accompanied by intense physiological activity. Genitals swell with blood, the pulse races, muscles contract involuntarily. Some people's mouths open. Others' faces contort. Many women's toes curl. In men, big toes often stiffen as their little toes twist. Both partners' feet may arch and shake. Sweat typically surfaces on both participants' brows, the heart pumps frantically, and breathing becomes fast and shallow. Both partners' nostrils may flare and seem to heat the air as it surges through them. With climax, each partner is clenched by contractions at consistent 0.8 second intervals. The human sexual summit is a paroxysm of pleasure. A warm glow envelops the waist and chest. The toes relax.

The emotions, too, generally go into a seismic convulsion. A mist of goodwill, wellbeing and lazy relaxation temporarily obscures reality. Both men and women may laugh or cry, or become uncommonly ticklish, although all these reactions are less common for men on the basis that they tend to show their feelings less anyway. Both sexes may experience a burst of creative thought since orgasm produces a near lightning storm in the right, creative-thinking side of the brain. Biological duty fulfilled, there normally follows a lengthy period of exhaustion, rest, and - frequently - sleep. 
  

All of this has a good deal to do with oxytocin, the "hormone of love" as it has been called. Oxytocin is a neurotransmitter synthesised by the hypothalamus at the base of the brain and stored in the posterior pituitary, from where it pulses out when required, which is during sexual activity and in childbirth, after which it prompts the desire to nuzzle and protect infants. Oxytocin induces feelings of love and altruism, warmth, calm, bonding, tenderness and togetherness, of satisfaction during bodily contact, sexual arousal and sexual fulfilment. It is during orgasm in both men and women that oxytocin floods through our bloodstream. Oxytocin released by female orgasm helps women lie still for a while afterwards. This increases the likelihood of conception, as well as making it probable that women will seek further coitus because they enjoyed it so much

Oxytocin is nature's sugar-coating to disguise the bitter pill of reproduction, the chemical basis for our capacity and longing for romantic attachment. It is the molecule that for 100,000 years or more has made us want to have sex face-to-face, adoring one another, and to live in permanent, monogamous couples
