In today's article, I have compiled an updated list of the top ten most-read questions in the history of blogs. As you can see, these questions (submitted by readers of "Sex and Psychology") cover a wide range of topics. However, most of them revolve around the same theme: "What is normal in terms of sex?" After reading these answers, you will find that the meaning of "normal" goes far beyond this!

10. How often do married couples have sex? (It has been proven that the frequency of sexual activity varies greatly, and the frequency seems to largely depend on people's age. It is also worth noting that having more sexual encounters is not always better, and as people age, the quality of sexual life is more important than the quantity.)

9. If a woman has frequent sexual activities, will her vagina become "loose"? (Some women's vaginas may become "loose" over time, but this is not because they have had too many sexual encounters.)

8. What percentage of women can reach orgasm through sexual intercourse alone? (According to the research I have seen, approximately half of the respondents reported this.)

7. Should the insertion be as deep as possible? (For most women, this may not be the case - but for some women, it definitely is. In fact, some women can reach orgasm by stimulating the cervix.)

6. Does the size of the penis really affect a woman's pleasure? (The answer to the previous question regarding deep penetration dealt with the length of the penis. Then what about the circumference? Research has found that women tend to consider the circumference to be the most important aspect of the penis size. )

5. Do women enjoy anal sex? (Many women enjoy anal sex. Research has shown that anal sex is becoming increasingly common among women nowadays. Although it didn't rank in the top ten this time, many readers are also curious about how to make anal sex more enjoyable.)

4. Ejaculation: Is it dangerous for a man to stop ejaculating during an orgasm? (Probably not. There is no scientific evidence suggesting that this practice will cause any problems. In fact, this is actually a common and very effective method that men learn to better control ejaculation in order to address the issue of premature ejaculation.)

3. "Is anal licking safe?" (Just like any sexual activity, anal licking also carries risks, but there are ways to increase its safety.)

2. Why do so many heterosexual men enjoy watching pornographic content featuring transgender individuals? (This is a common sexual interest among men, and contrary to common belief, most men who are attracted to transgender men or women are not homosexual.)

1.I want to watch my wife sleeping with someone else. Is this normal?
