The cycle of sexual response human has different phases: sexual desire, sexual arousal, orgasm, and ends the resolution phase.
Sexual desire (libido) depends on the functioning of the endocrine glands and metabolism. Also the sexual desire depends on the brain (cortex and subcortical layer) and the sexual centers of the spinal cord. All the centers will interact with each other and form a single system.
The degree of excitability sexual centers and the libido of an adult human is dependent on the level of hormones.
Libido (sexual desire) depends on the innate characteristics of the man, related with the anthropology: the brunettes attraction stronger than blondes, stunted the most intense stout; overweight women for sexual satisfaction, require less effort and caresses, and of the bad; the southern sexual desire stronger than in the north.
The difference in excitability and sexual men and women
Men and women, and also different sexy excitability. The man sexual arousal much higher than that of a woman.
If the man's excitement increases rapidly, erection occurs after orgasm and ejaculation arousal and erection, disappear completely, the woman, the accumulation of excitation — a process long enough, which requires caresses from a partner. And after orgasm, the excitement slowly disappears.
However, in the case in which a woman has an orgasm has not arrived, the outflow of blood from the genitals is very slow, for an hour and even more. Lack of orgasm can occur because of insufficient stimulation of erogenous zones or too fast during sexual intercourse. Then the woman is lacking sexual satisfaction, not sexual discharge. This leads to the fact that women will appear back pain, pain and a sense of heaviness in the lower abdomen. To slow the outflow of blood occurs by a stagnation of blood and lymph in the pelvic organs, promotes the development of inflammatory processes, painful menstruation and leucorrhoea (vaginal discharge).
Lack of orgasm is very harmful for the health of women, as well as in the absence of discharge after the strong excitement in women occurs the state of frustration — painful nervous tension with a sense of dissatisfaction and emotional response.
In the case of excessive excitability sexual centers of men, ejaculation occurs very rapidly. It is called humilis recipis men. If the men are not there is still an erection or weak erection of the penis, this phenomenon is called impotence.
The sensuality of women and men develops in a different way.
The majority of women, the sexual desire develops 25-28, sometimes up to 30 years. After the age of 45-50, sexy, sensuality reduced. In menopause, the sexual desire can increase after menopause disappears. Some women, this is stored up to 60 years and longer.
Men all over takes place in a different way. Up to 25 years, the need for a sexual life much higher than that of women. The sexual desire reaches its maximum at 28-30 years, after which it gradually starts to decrease.
When the age of men is approaching the"wilting", his sex life is often activated. This happens, rather, for reasons of psychological nature, fear of impending old age.
Reduction in specific power, it does not happen to all men. Some preserve sexual potency up to old age.
The lack of correspondence of the periods of increased sexual sensitivity, and the ignorance of these nuances can bring to the brawling pair.
The sexual satisfaction of a partner in a great measure dependent on another partner. The sexual act is the only double-physiological human act. Therefore, if the partner for sex or the spouses want to keep a long relationship, it is necessary with understanding and patience to treat the other, for the possibility to identify the erogenous zones of the partner and, if men, the erection is not too long, a little more to stimulate the partner, until sexual intercourse. More often in women of this erogenous zone is the clitoris.
