In adolescence, when the time comes for first love, young men and girls suddenly discover that they have a completely different idea of how lovers should spend their time. The young man is sure that their main task is to establish an intimate life as soon as possible and as often as possible to indulge in the joys of sex. The girl thinks that the most beautiful thing in reciprocity is walks under the moon, long conversations on the phone and dizzying kisses. Despite the true love for his hero, she is not at all, as they say, "go further." This is due to the fact that for the desire for sexual intimacy in the human body meets the hormone testosterone. It is produced both in the female and in the male body, but its amount depends on the person's age. At the young men at the age of 16-20 years the real hormonal storm rages, being in the power of which they constantly think about sex. And they often do not care about its quality, the main thing is the fact itself.
And in the female body during this period, the production of testosterone is not too great and it grows very gradually, so sensuality slumbers, and the young lady often agrees for sexual relations, only yielding to the wishes of the lover, and does not always get satisfaction from sex.
By the age of 25, the male body usually reaches its hormonal peak, which has been held for about 10 years. The girl all this time continues to increase the production of testosterone and the formation of sexuality. So at the age of 28-32 years in the relationships of many couples sexual harmony is established, because at that time the female upward line of testosterone and the male descending line are suppressed. A man who survived the period of hormonal storms that pushed him to search for new impressions and sensations becomes more calm and restrained, he is set for a long relationship with one partner. The girl wakes up sensuality, and she begins to enjoy sexual relations - about 20% of the fair sex only after 30 start experiencing orgasm.
In the future, the lines of the "testosterone cross" diverge, because after 30-35 years the male testosterone production falls steadily by approximately 1% per year (some factors may accelerate this process, for example, with obesity, the "drop rate" can reach 10%). In a man's life, sex ceases to play such an important role as before. Meanwhile, the girls all the way around: all this time the development of testosterone in the female body is steadily increasing and reaches its peak by the age of 40. Sex becomes necessary for her, but her peers do not experience such a need, which, like herself in her youth, now needs warmth rather than bright erotic experiences.
And the girl's body in the meantime is slowly preparing to "fold" the banners, because the climate is not far off. True, before it occurs a hormonal outbreak, which also determined the saying "in 45 baba berry again." Something similar can happen in men, so they have "gray hair in a beard, a devil in the rib." At this age, stable marriages often break up and different-age couples are born. And, if earlier the man was older than his wife, then recently there was a tendency to the appearance of couples, in which the woman is much older than her partner, in Europe the number of such marriages is about 9%.
In the later sexual life of people in recent years, too, there have been changes. If before it was assumed that with age, the person's intimate life should gradually come to naught, but now the views have changed. Today it is believed that the longer a person will be sexually active, the better. And the number of people who, despite the retirement age, continues to enjoy intimate pleasures, is steadily growing, more than half of men in 60 belong to them (15 years ago they were almost half as many). And doctors strongly welcome it, because it has already been proven that the mechanisms of aging are "afraid" of sex, and those who do not deny themselves to it, they are launched much later.
