This author argues that women so they feel like making love as men, but differ in their fantasies and arouse their libido circumstances.
Men are more aroused to visual sexual stimuli and signs of youth, health and fertility in women, however women are more attracted by signs of commitment, status and material resources, women's sexual appetite is more sensitive, which is why women have a greater tendency to bisexuality. While
libido in women is more intense, is also less constant, and social and emotional context is broader, and is "every bit as durable in the course vital.

The women begin to have early sexual experiences, they also have more lovers before marriage and perform more sexual experimentation with their partners. Thus we see women who enjoy promiscuity, others hire the services of taxi boys, some are bisexual or lesbian. Today women are beginning to express their sexuality from early adolescence to old age. H. Fischer believes that "a return, perhaps, ancestral ways of life of women.

human sexual desire
The human sexual desire originates in the hypothalamus (primitive part of brain), then through a complex network of connections and reactions secretes chemicals that are poured into the blood and stimulates the gonads to produce androgens, particularly testosterone and estrogen, particularly estradiol. Adrenal cortex also is involved in the function of human eroticism.
The balance of all these substances that lead to bed is extremely complex. Testosterone has an important role.
Women with high testosterone are more sexual desires as well as more thoughts about sex than women with low testosterone levels also make love and masturbate more often.
At the time of ovulation, when levels of estrogen and testosterone are very high, some women increase their sexual desire, others feel after menstruation, such as a delayed effect of high levels of testosterone that occur at the half of the menstrual cycle. It is not known whether testosterone has peaked in the fall, but the testosterone levels in men are higher in the months of November and December (in the northern hemisphere).
Higher levels of testosterone in both men and women occurs around sunrise.
We can say we're just walking hormones, no way, expansion of our cerebral cortex allows us to decide when, where, who and how to express our sexual impulses. We may also decide not to express them.
sexual habits of men and women differ, and they originate mostly in the cortex of their brains., But also differ from the generic point of view.
Men are more likely to remember certain aspects of past sexual episodes such as a garment, a flavoring in particular. The female psyche is less subject to this type of "conditioning" Men stimulates the visual and more frequently used visual pornographic materials, not surprising The $ 500 million currently generated by the pornography business in the U.S. is due almost exclusively to men spending.
Helen Fisher says that "this need to look male has a Darwinian effect. By looking at a woman, the man judged the health and vigor of it. To raise their testosterone levels get sexual stimulation that leads to what appear to woo young and healthy, and fertile "
While women are also excited the pictures, to a lesser extent than men, they will produce greater arousal words, images and themes of romantic movies and stories, they include sexual fantasies affection and commitment are interested in words, are more sensitive to physical touch and more interested people. These preferences for the talk, caresses and romantic relationships with partners previously known "is most likely an evolutionary purpose, the woman you risk getting pregnant when you love."

The porn film producers in the U.S. have begun to consider these treats to attract female and female customers in his productions include some dialogue and appearance romantic argument.
When and how we fell in love Helen
reveals the key because we fell in love with someone, it is important clues as time and cultural elements must be found in time to fall in love, also speaks of the unconscious that we profile on the basis of our experience our childhood, our parents, our environment, from school, when we get the right time and find the person who fits that profile, that is when the brain circuitry can be operated and produce chemical reactions, but that is not going to choose a particular person in man is very typical of beauty and youth, women more impressed with the wealth and good position, the woman gets more for the eyes, the woman is more sensitive to the word and detail.
When we fall there is a projection in the brain chemistry of brain circuits. Fisher studied the brain in love and discovered several things:
1) found that dopamine, and serotonin norepirefrina are substances detected are as natural drugs when we fall in love, that kind of madness that accompanies the state of being I love produce high dopamine and norepirefrina nveles, and the low level of serotonin,
2) addition of dopamine to increase testosterone sex hormone, is associated with euphoria and dependence, which are symptoms of addiction,
3) the high level of norepirefrina produces euphoria and loss of appetite,
4) the low level of serotonin has to do with the obsession to be with the beloved, of wanting to be with the beloved.
Fisher arrived on these results based on two studies. One, made with the help of a neurologist at the Albert Einstein College of Medicine of the University College in London, Lucy Brown, who was to scan the brains of 34 people while looking at the photo of the person you feel a physical attraction. As they did, the images of these brains showed elevated levels of dopamine or norepinephrine, or both, as well as a decrease in serotonin levels.
Other research was a survey consisting of questions and answers that made 800 people with the precondition that each had lived, ever passionate love. 80% of the responses revealed that passion lasted only 1 to 3 years. Thus
Fisher concluded: "The Passion energizes the brain more or less the presence of three neurotransmitters and has a duration of between 1 and 3 years later, the love and trust can extend the life of the couple for a decade or more. "
A survey of Cornell University, New York, points in the same direction: five thousand people from 37 different cultures were interviewed agreed that the passion lasts between 18 and 30 months
Studies of women in very different cultures and tribes, was the most common term for divorce in 4 years after marriage, that study also other species that look similar links appear similar to human behavior patterns, and develops the theory of 4-year reproductive cycle.
seduction and infatuation change over time, seduction first is impulsively accelerated, but that first time calms down calms down, there are other stages of the couple, where some come to grow rich to feel good and others see parties negative than positive partner, may be beginning to break, seen as it's over love.
According to Dr. Otero Lozada, the process or act of falling in love, could be related to a process of memory in the limbic region of the brain, although both men and women are the romantic love with the same intensity the process infatuation and lust are similar in both sexes, but women being more moody show more emotional swings, in addition to the cultural differentiation of the brain is a continuous, process and internalize things a different way, according to that Dr. Otero Lozada CONICET researcher at the Laboratory in the laboratory of sensory emotions, about falling in love talking about different kinds of love and chemicals associated with it
truth according to Dr. Otero is that the passion fades because as the body adjusts to hormone levels and decreases over the years the state of excitement and euphoria, to Otero Lozano, the problem is the loss of passion, but the link becomes calm but dull, safe but dull, durable, yet claustrophobic, the other can not produce any motivation, let be, that can lead to depression, quality work and the amount of emotion to lead to more emotional and sentimental feelings,
She is a wonder drug tolerance, if a person falls in love many times, it loses the ability to love, she says that if there is need of new incentives to raise the capacity of love, if one can speak of a certain tolerance since it would require more intense stimuli to reach the crush, as well as state and vasopressin, increases sex, sex increases serotonin and mood, laughter also chocolate, increase physical activity of
When spoke passionately low serotonin levels, that can lead to illness of an obsessive love, as was the case in the history of Spain Juana la Loca and Philip the Fair, but really about jealousy.
Alcohol lowers serotonin levels, so after a night of drinking men and women are often more readily to the passion.
arises Antidepressants Dr. Otero, people who consume them endanger their ability to love, to keep them stable serotonin, are maintained in the brain longer than normal, resulting in gonadal depression, it that makes people feel lethargic, listless, discouraged, but that does not stop falling in love, though they may be more complicated.
"In the passionate love we become obsessed by our beloved and we are ecstatic. Es un estado que no podemos controlar", sintetiza Fisher, Y si la pasión es un estado de fiebre que toda persona disfruta cuando vive y anhela cuando no la tiene, quizás sea oportuna la conclusión de Hoffmann: "Pedirle a la química que haga todo es ponerle un plazo biológico a la relación".
Una verdad que no puede perderse de vista. Hoy las relaciones amorosas empiezan donde 50 años atrás las parejas concluían. "Las relaciones tradicionales ponían primero el acento en el desarrollo del vínculo afectivo, emocional, familiar y recién después venía el sexo. Ahora es al revés. El sexo está al principio y después hay que construir la intimidad, la ternura y un compromiso", analyzed psychoanalyst, Emiliano Galende.
"The commitment to another person or persons, including an unconditional commitment and, indeed, a rate commitment''until death do us part, in good times and bad, wealth and poverty ' ', it seems more and more into a trap to be avoided at all costs ", describes the critic of postmodernism, Polish writer Zygmunt Bauman, in his book" Liquid Love "..
Perhaps a formula for surviving these times is, as suggested by Hoffmann, "build the love through acts of trust to strengthen the bond and evidence of effectiveness that each has to contain another ".
According to brain expert at the University of Edinburgh, Gareth Leng, the hormone oxytocin helps forge permanent ties between lovers after the first wave of emotion.
The hormone acts" by changing the wiring "of thousands of millions of brain circuits.
maternal behavior
Leng said that oxytocin helps strengthen the bond between a mother and her baby, and occurs both during childbirth as an orgasm.
What it does is act as a " central switch, and the brain, which opens up new patterns of interaction between nerve cells.
But, in explaining why some brains not fall in love, Leng physiological gives you an excuse to many (and many) fans at the beginning of a relationship and detractors of "tomorrow."
And those who have fewer brain receptors for those needed to receive oxytocin may have difficulties in trying to establish permanent links with their partner.
Research has found that the hormone that is produced in large quantities by the brain during delivery and when there is sexual activity, it is important to induce maternal behavior in animals. Leng
conducted their studies in mice of the prairie and explains that "the prairie mice have only one lifetime partner, and that bond is established during 48 hours of intense sexual activity which is also the first sexual experience
"During that period, large amounts of oxytocin are produced in the brain," he adds. "Prairie voles have oxytocin receptors in different parts of the brain and the scientists found that blocking these receptors, no such link in the females."
"Understanding the process is essential to understand how drugs can influence the temper and behavior, for better or for worse," he says Leng.
Desire, romance and attachment
Romantic love is linked to the desire: this is the need for sexual satisfaction and attachment, feelings of calm , Security and unity with a pair of long duration.
desire in both men and women is associated with testosterone. Romantic love is associated with dopamine and perhaps norepinephrine and serotonin, and feelings of attachment between the male and female are primarily produced by oxytocin and vasopressin.
romantic love emerged as the men and women need to focus their attention on the couple as an individual chosen from the crowd, and the brain circuitry of addiction in male and female were developed to allow our ancestors lived with your partner enough to raise a child together during their childhood
These three brain networks, desire, romantic love and attachment are multifunctional that is used to make and keep friends more enjoyable adventure, toning muscles and relax the mind
Romantic love can not be encouraged to maintain a relationship or fall in love with another person and start divorce proceedings, attachment allows us to express a genuine affection for the couple, children and friends.
desire.
desire and romantic love are two very different feelings, in fact few people in Western society confuse the feelings
The same applies to other people and cultures easily recognize these feelings. Scientists have discovered that the desire and romantic love is associated with different constellations of brain
The desire is related to a hormone, testosterone. Men and women with high circulating testosterone levels tend to develop greater sexual activity, and mature women who take testosterone increases sexual desire. Women feel more sexual desire when they are about to ovulate, because it increases testosterone levels.
As estrogen levels are decreasing with menopause, levels of testosterone and other androgens are exposed. In a study of middle-aged women, nearly 40 percent complained not have sex enough.
We saw men and women are sexually stimulated differently.
What triggers sexual desire when we fall in love?
Dopamine, responsible for romantic love, can stimulate the release of testosterone, sex hormone of desire.
When men and women affected by depression take a medication that increases dopamine levels in the brain, sex drive generally improves.
Generally speaking, dopamine and norepinephrine arouse sexual desire most likely because testosternona levels rise.
reverse is true, can trigger the desire in love?
The desire does not necessarily lead to passion and obsession of romantic love. Athletes who inject synthetic androgens to increase their muscles do not fall in love when they take these drugs
"The brain circuitry of desire does not necessarily ignite the fire of love." (H. Fisher)
This does not mean that sexual desire Romantic love will never accrue to
is why it is dangerous to copulate with someone does not want any commitment it may be that the brain chemistry and ends up falling betray us ..
attachment.
As time passes you love becomes more relaxed, deeper obsession ecstasy dissolve, but if we're lucky, magical feelings are transformed into new ones such as security, quiet, comfort, the union with a partner.
Brazilians have a saying that distinguishes both poetic feelings and states: "love is a mature look and a smile"
What are the chemicals involved in this feeling of merging with the long-term partner? . Most scientists now believe that vasopressin and oxytocin, hormones closely related to each other and produced mainly in the hypothalamus and the gonads produce many attachment-related behaviors
Nature has endowed mammals of a chemical to develop the paternal instinct: vasopressin.
Oxytocin and vasopressin are produced in the hypothalamus and in the ovaries and testes. Oxytocin is released in all female mammals (including women) during the birth process, which allows contractions of the uterus and stimulates the mammary glands to produce milk. Today it has been determined that oxytocin also stimulates the bond between mother and child.
Today many believe that oxytocin is also related to feelings of attachment between male and female adults.
These hormones segregates at the height of sexual intercourse, during stimulation of the genitals or nipples during orgasm. During orgasms increase levels of vasopressin and oxytocin men and women. These chemicals "Embrace" are contributing to the sense of fusion, closeness of attachment that is experienced after having enjoyed a pleasant sexual encounter with the beloved. Summarizing
attachment chemistry can trigger the desire and the chemistry of desire can trigger expression of adherence
However, these hormones can have negative effects each other. High levels of testosterone can reduce levels of vasopressin and oxytocin, and high levels of vasopressin can reduce testosterone levels
The man with high testosterone levels marry less often, are more adulterous relationships, spousal abuse and comment divorce more often.
When the marriage of a man staggering increase testosterone levels, and even more when you divorce. The unmarried men tend to have higher testosterone levels than married.
also happens that when the man's attachment to his family is on the rise, testosterone levels drop. Even when a man has a baby in arms, their testosterone levels drop.
Perhaps this explains why men and women who form stable marriages spend less time making love.
feelings of attachment may decrease the ecstasy of romance replacing it with a sense of profound union with a partner.
neurologically seems that we are capable of loving more than one person at a time. You can feel deep attachment for a spouse who is a long time, while you feel romantic love for someone of his social environment while experiencing a sexual desire while reading a book, watch a movie without having any relationship with others
This author argues that women so they feel like making love as men, but differ in their fantasies and arouse their libido circumstances.
