Sexuality and human biology

Sexuality and human biology

Sexuality is a central aspect of the present human being throughout his life. Sexuality covers sex, pleasure, eroticism, privacy, etc.

Biological foundations of sexuality

Like the rest of the primates, human sexual arousal has late reproductive, and social linkages. The difference in the human species is that in addition to reproduction, sex is added the component of enjoyment and pleasure.
Freud pioneered to say that sexuality is a much broader concept that includes all aspects of human life, is not only sexuality. This means that the person as a whole is a be sexed and their sexuality is not restricted only to a few organs but that is part of all of their human biology.
Sexuality covers sex, pleasure, eroticism, privacy, etc. As well as psychological, cultural, ethical, physiological and social factors.
Sexual arousal in the human species has primarily reproductive purposes, as it is the case with other primates. But, in addition to the establishment of social links, humans give special importance to sexuality as pleasure-seeking.
Human sexual
are complex, result of intelligence and culture, and does not totally controlled by the sexual instinct as it happens in most of the animals. They vary greatly depending on the person and the cultural trends in force and, in the human species, the woman has always had the weight of the preservation of the species.

Sex drive versus conservation boost

Nature, gifted men and women pheromones and sex hormones, which facilitate the mutual attraction and purely instinctive way to ensure the conservation of the species.
Sex drive together with the conservation, are those who lead sexual life. The sexual instinct is primary, emerged as a response to a need that satisfy, sex. But as two people are involved in this primary need, there is a reciprocity, giving and receiving. Thus, the need ceases to be primary impetus to become much more.
Sex drive is aimed at the search for partner and has evolved differently to romantic love and affection.
According to anthropologist and researcher Helen Fisher, romantic love is stronger that the sex drive because one of the main characteristics of falling in love is the desire for sexual exclusivity, be very possessive with the beloved. In the scientific community are known as “surveillance of the couple”.

Why love when they mean sex?

It is normal in men and women to sexual intercourse where the pursuit of pleasure is mutual interest, because in this way the sexual satisfaction is higher. When you have sex with someone, is being shared pleasure.
However, as claims Punset in his book the journey to love: “sexual desire and love are different things and the brain pathways that govern them also are different”.
Most people, at some point in your life, seek something else than pleasure in sexual intercourse and not for moral reasons, but because they want to find a meaning different from the sexual act.
When a couple makes sexual intercourse and at the same time they are in love, the pleasure extends to another level. Pleasure, would not be an end in itself but, something much more than a biological need and the pleasure-seeking hedonistic, something so deeply, as it can only be: the desire to love.

Is love in the sex act so important?

When there is love in sexual relationships, the emotions are more intense because arises a more intimate union between two people. There are no obligations, but a share and love make sexual intercourse more mature, balanced and above all full.
However, as stated by Helen Fisher: “romantic love is very dangerous. It carries with it a great happiness and a great sadness”and who is prepared to suffer?

Sex and love, the life force

The scientific populariser Eduardo Punset gives us a new definition of love that encompasses the evolutionary aspects such as species and perpetuate life force: “love is an evolutionary instinct of merger with another organization, even prior to the emergence of sexual differentiation… Without love there is no life. It is a constant evolving.”
“Love is pure chemistry,” says Helen Fisher, but still we do not know all the processes of falling in love or all the keys in human sexuality.
In the East, there is the philosophy of Tantra, whose main objective according to Ana Elena Costa, is to develop sexual potential, to achieve the spiritual evolution. It is to consider sex as a transcendental union. It is said that when the sexual practice is developed with love, comes the kundalini, also considered the power of life.
