1. Freud pointed out: All activities of all animals are controlled by sexual desire. Males work hard and fight to get the right to mate with females. This is not entirely true, but at least for people in love, Freud's words are correct.

2. If a middle school student is only satisfied with flirting with his pretty classmates, then he will definitely not have a big future. A truly good student should believe that "there is beauty in books" and should make up his mind to marry the best woman in the future.

3. When dogs are mating, even sticks cannot open them; when people are having sex, just a few knocks on the door can turn them off. This is because animals only satisfy instincts, while human sex is full of rationality.

4. How can students who are full of sexual fantasies read textbooks? How can an employee who is full of sexual fantasies do a good job? One thing is for sure: there are a group of people who are ruined by sexual fantasies.

5. An erection is not entirely a sexual signal. Sometimes it is just a reminder that it’s time to pee.

6. A coquettish woman may not be sexy because she has released too much sexual energy; a sexy woman may not be coquettish because she has abundant sexual energy in her body.

7. Sex is definitely more than just a kind of enjoyment. In fact, you have to pay a lot.

8. A truly pure girl can even make a playboy want to protect her; a truly slutty woman can make a shy boy want to take action.

9. Sexual repression and sexual indulgence are the same as physical and mental health. It is even worse to go back and forth between depression and indulgence.

10. China is a big country with hepatitis B and dental diseases, and AIDS is also on the rise. Therefore, Chinese people are actually not suitable for one-night stands. Because the chance of cross-infection is too high! And I believe that the sicker a person is, the more likely he is to have a one-night stand. We can also put it another way: the easier it is to have a one-night stand, the easier it is to contract the virus.
