I believe that many people have heard the phrase, that is: “women 30 fierce as a tiger ~” then this folklore rumor whether there is no scientific basis for it? Most women in the age of about 30 years old, is indeed the most vigorous period of sexual desire. From an objective professional point of view, people to the age of 30, in addition to the natural sexual indifference, normal women will inevitably have demand. The woman’s shyness at this age has long been gone, and she has long regarded sex as a very important thing in her married life to please herself and others, so they are often very open in the face of their partners. 30 years old is a period of high estrogen secretion, with the secretion of estrogen women’s libido becomes strong, the couple’s life becomes urgent, in fact, this is normal. The study of a university in the United States found that the 30-year-old women’s brain creative cells are most active, more imaginative than men of this age, and the content of the fantasy is mostly related to “sex”. But with the rapid development of society in recent years, people’s living standards have gradually improved, resulting in children inevitably have to eat too much junk food with too many hormones, making their own hormone content too high, resulting in precocious sexual maturity. In terms of sexual awareness, some children may also be exposed to books about sexual innuendo in advance, which may also lead to their psychological impact and even produce inexplicable physical reactions. From the above points, it seems that although the so-called folk rumors have some scientific basis, we should not make generalizations and generalizations. Women, like men, can have a very high sex drive at different ages. This situation will be affected by the combination of personal experience, personal physical condition, growth and survival environment and other factors. Therefore, we should take a proper look at the level of desire for physical needs of women at different ages.
