First, from a psychological point of view, everyone has the psychology of liking the new and hating the old. Psychologists have done an experiment: put a male monkey and a female monkey in a big cage and observe their mating frequency. Results The mating frequency was the highest on the first day, and then decreased gradually. After a week's observation, mating becomes less and less; At this time, the female monkey was taken out and put into a new female monkey, and the mating frequency increased as before. People also need new sexual partners. Therefore, the infidelity of women (men) is not entirely due to moral decay. Throughout history, most people who cheat are successful people, highly educated people and even cultured people. Second, judging from the current social atmosphere, it also provides people with a social basis for derailment. Nowadays, women (men) have lovers, confidants and sexual partners, and they are no longer the objects that people spit on, even an honor. Many people think it is an indispensable way of life and a reflection of improving the quality of life. Modern people are no longer victims of feudal society. They are very concerned about their physical and psychological needs and are very open-minded. The popular slogan is to do what they want. Third, ideas from people. Now people's concept of chastity is becoming more and more indifferent. Young men and women born in the 1980s and 1990s no longer attach importance to chastity. Nowadays, unmarried women, from middle school students to college students, know a lot about sex and are very casual. Some junior high school students and even primary school students stole the forbidden fruit. It is nothing new for college students to find a one-night stand, let alone live together. The university has allocated it, so it is natural to say "bye-bye". Unmarried men and women can pursue sexual satisfaction. What do you mean by married people? Of course, married women's infidelity does not rule out the following reasons: 1, loneliness. Mainly due to work, husband and wife often separate, plus the husband does not often communicate with his wife to cultivate feelings. After a long time, it will inevitably make them indifferent. The wife has a lonely heart. At this time, if there is a suitable opposite sex, it will easily lead to the wife's derailment. 2. Revenge. Mostly because her husband is promiscuous and madly in love outside, once his wife finds out, it will be exposed. Stiff quarrels often occur between husband and wife, and it is not surprising that the wife is angry and revengeful. 3. Superior conditions. Mostly because the wife is beautiful, has a superior education and social status, and has many suitors around her. It's easy for a wife to feel unworthy. This will make her naturally cheat. 4. The life of husband and wife is not harmonious. Most of this type is because the husband has sexual dysfunction and cannot live a normal husband and wife life. But sex life is a very important part of a couple's life. Or because my husband is busy at work, he can't be warm and considerate. Over time, it will lead to discord between husband and wife. This will make her feel bored. So as to seek new spiritual sustenance outside. Fourth, women who want to prove their charm are still married and have children, especially from the age of 27-28, women gradually move from girls to young women, and they begin to doubt whether they are still young and attractive to men. At this time, women also began to question life and resist aging. Especially those women who work hard for their husbands or give up their careers, always feel that they have missed the best years of their lives. It seems that I have never enjoyed life. So, when they see a man who likes them, they want to learn the plot in the book and the movie to have an extramarital affair. Fifth, adding a passionate sexual life to love is often overlooked by couples who are drowned in daily chores in marriage, but it is also an essential thing and should be placed in a less important position. However, women are always in a hurry. Even if they are afraid of being treated as a dissolute woman by their husbands, or when women need more sex life and can't satisfy it at home, cheating has become a new attempt to have fun. I just want to get rid of the boring life. When men and women feel that life has become the same and unchanging, she will begin to yearn for change and adventure. These women are not looking for marriage outside, let alone trying to get rid of the existing marriage, but just to adjust their ordinary lives. Influenced by modern social atmosphere, let's experience the feeling of extramarital affairs. Life is like this. It creates opportunities for men and creates the same opportunities for women. When men choose women, men are also being chosen by women. Men cheat women, and women cheat men. Hehe/The world is so wonderful.
