5 types of sexual relationships a man should try in his lifetime (adult novel about sexual knowledge)

A man should try 5 kinds of sexual relationships in his life. A man consulted a psychologist in distress on a midnight radio program: he likes to have sex with a girl, but absolutely does not want to marry her. But the girl wouldn't let him go. He said distressedly: He was sure that he did not love her, but he wanted to be with her. Was this a disease?
Of course, a psychologist's forte is to diagnose such people. The doctor thought that this was certainly not a disease.
But it is the nature of men. The doctor believes that men are animals by nature and that sex is definitely not love. The problem is that guy has a newer trouble. In addition to that girl, he has had "relationships" with different types of women many times.
This "relationship" made the audience angry. Many people accused the man of being like an animal. But the doctor is a scientific and rational person after all. She analyzed that this is just a normal phenomenon from the perspective of men's sexual psychology structure.
The doctor also said in a very feminist way that a man should have many kinds of "sex" in his life to be complete.
As a man, I actually agree with the doctor's scientific analysis. The doctor also named this the phenomenon of male "cheating".
Discussing men's infidelity seems to be an old and boring topic. When we talk about this issue now, it is no longer limited to married men, but refers to a kind of potential psychology of men in general. Many men do not stop cheating just because the topic is old. Observing cheating is a fun game. The problem is that if only bad men cheat, people might forgive them. But what really makes me pay attention to this matter is the marriage accident performed by a loving couple. This couple is a talented man and a beautiful woman, and their love for each other is as dramatic as a drama. Only I know this is true, because love cannot be concealed.
But even in such a family, the outbreak of the story makes people feel helpless. The man actually hired a prostitute and later had a good relationship with the prostitute, which lasted for three years under our noses. What a horrible man he is, he can be loving with his wife while enjoying sex with that prostitute?
After the incident broke out, the man faced my questioning and calmly said, "Actually, this has nothing to do with love. I love my wife, which is a spiritual love; and the relationship with that woman is a physical love. Tell me, which one can I give up?"
I have no idea. But I know that being a man and actually having only one sex in your life is a terrible thing.
Sex is the most direct way for men to experience life. This kind of sex is just the animal nature of men, the body's instinct, which has nothing to do with moral concepts or rules.
After research, a medical scientist said that a man should experience more than five kinds of sex in his life. The first is sexual enlightenment, followed by sexual happiness, sexual diversity, sexual beauty, and long-term sex (partner). These five types of sex summarize a man's life. This is the scientific explanation.
But the problem is that science has always been a snobbish tool that humans have selectively used. This discovery cannot serve as a scientific basis for men to seek pleasure. The man finally divorced and the child went to her mother. And he became a moral outcast because he didn't have the courage to be with that woman. This is the result of men's pursuit of "diversity".
Cruel, but not beautiful.
