Research has found that sexual life may affect the composition of bacteria and "virgins" can also be identified

Men have neither a "hymen" nor a "guardian sand". Their innate physiological conditions determine that it is difficult for women to verify a man's chastity. Although many people still have a "virgin complex" today, how to identify a "virgin" is meaningless. On the contrary, when it comes to the method of identifying a "virgin", many people say it is "awesome".

In May last year, a team from the Department of Biology at Indiana University, Bloomington, specializing in "Microorganisms and Environment" published a research paper on how to identify "virgins" in the journal "PLOS ONE" .

The researchers used a technology called 16S rRNA sequencing. 16S rRNA is a component of the ribosome (the place where proteins are synthesized) of prokaryotes (that is, organisms without a formed nucleus). There are obvious differences in the sequences of 16S rRNA between different species. By analyzing this difference, we can tell which species possess these 16S rRNAs.

Nielsen selected 18 young men aged 14 to 17, including 7 Caucasians, 7 Blacks, and 4 Latinos, and had their genitals and coronal sulci removed every month for the next three months. A DNA sample is collected from the urine. Using the 16S rRNA sequencing technology just mentioned, Nielsen successfully detected 58 different bacteria.

Interestingly, the proportions of certain bacteria change as the environment changes. For example, men who have undergone "circumcision" or "circumcision" surgery have a higher proportion of aerobic bacteria (such as Staphylococcus) in the coronary sulcus, while men who have not undergone similar surgeries have a higher proportion of aerobic bacteria (such as Staphylococcus aureus) in the coronary sulcus. The proportion of anaerobic bacteria (such as Porphyromonas) is higher.

More interestingly, sexual activity may affect the bacterial composition of the coronal sulcus and urethra. Several bacteria, such as gonococci, have been detected in previous studies on adult men, but were almost absent in this experiment. Ureaplasma, Mycoplasma and Ciliatomycetes, which are vectors of sexually transmitted diseases, are only found in men who report that they have had sexual relations with their partners. This seems to prove that "sexual life can change the bacterial species in male genitals." hypothesis.

However, some men's genitals are born with a lot of flora that are only found in female genitals, just like behaviors other than sexual intercourse can also cause the hymen to rupture. Therefore, “non-virgin” or “non-virgin” in the narrow sense may both fall into the category of “unjust, false, or wrongful conviction.”

The above introduction is a scientific method for identifying virgins, which is too high-end. If women want to quickly distinguish between virgins and non-virgins, you might as well try a few interesting methods:

1. A virgin peeing in the toilet is completely different from a non-virgin. He rushed into the toilet in a hurry, couldn't hold it in before he even got to the urinal, took out the urinal and spilled it. His pee was like a fire fighter's high-pressure faucet, spraying on the opposite wall, bouncing back and drenching his hair. A drowned man is a virgin. Instead, he walked slowly into the toilet, walked to the urinal while looking around, put one hand in his crotch and dug around, just like a careless housewife looking for her keys in her bag. It took her half a minute to find her tools, and then He just stood there motionless, as if thinking about a world problem. When everyone who went to the toilet to defecate had finished, he whistled to himself and came out. My face was almost pressed against the wall, and my waist was almost bent. But when I finished the work, I found that my cotton shoes were still wet. This was definitely not a virgin.

2. Virgins generally don’t go topless in front of girls, let alone wandering around in the streets wearing big-crotch shorts. They only like to wear tight tops to show off their pectoralis major muscles. It's different for non-virgins. When the weather gets a little hot, he can't wait to take off his shirt, for fear that others won't see his belly. If he sees a girl passing by, he will shake his belly. It looks like a sea of ​​flesh churning.

3. When taking a bath in a large bathhouse, virgin men will tie a towel around their waist to cover their shameful parts. When taking a bath, they usually shyly turn their backs to everyone, but they pay attention to other men's shameful parts, and then carefully talk to them. own comparison. The non-virgin guy would come in naked, with his lower body swaying from side to side, like a hookah hanging on his waist without even realizing it. He said he didn't know, but when he was talking to others, he fiddled with it with his fingers intentionally or unintentionally, as if he was teasing a parrot.

4. Medical books prove that on the inside of a boy’s arm joint, about an inch toward the palm, there is a line similar to a knife mark or fingernail scratch. It is usually very obvious. This is the so-called virgin line. . If you have had sex, this line will disappear, just like the virgin's gecko sand. It is very scientific and the identification method is also very simple. As long as the majority of female comrades lift up the boy's arm and take a look, everything will be clear

5. When a virgin sees a beautiful woman, his eyes will straighten. He will stare at the beautiful woman’s face for a few seconds and then immediately turn to his shoes. When a non-virgin man sees a beautiful woman, his eyes will light up. After staying on the beautiful woman's face for more than ten seconds, he will immediately turn to the beautiful woman's chest. Then, his eyes will patrol back and forth on the beautiful woman's face, chest, waist and legs.

6. When a virgin sees a beautiful woman approaching with her high breasts, he will subconsciously cover his lower body and take a few steps back. If he is timid, he will turn around and run away. When a non-virgin man sees a beautiful woman approaching with her breasts high, he will shed tears and say: Wow! It seems like a pair of big eyes are staring at me!

7. A virgin will not pass under a woman’s bra and underwear. Not only do non-virgins have to wear it, but they also have to use their hands to push the bra off their heads. Men who have been virgins many times will still look at the bra and laugh and say: What a big tool for keeping a mistress!

8. If you are a virgin and you hold his hand, his lower body will react. If he is a non-virgin, even if you pull his lower body, his reaction will be as slow as the Chinese team shooting.

9. When a virgin hugs a girl, he or she bows down; when a non-virgin hugs a girl, he or she hugs with her waist straight.

10. A virgin will be at a loss when selling sanitary napkins, and his face will be as red as a date. When a non-virgin man goes to a place selling sanitary napkins, he will leisurely look at the brand and price, and then suggest to his girlfriend whether to buy a thicker or wider one.

11. Before having sex with a girl, a virgin will get into bed and get under the covers; before a non-virgin has sex with a girl, he will get into the bathroom and take a shower.

12. Virgins don’t know how to use contraceptives, but non-virgins use them very skillfully.

13. A virgin will be silent or even cry after having sex with a girl; a non-virgin will laugh after having sex with a girl. After laughing, he will say: Sister, let’s exercise together again.

14. Virgin men appear to be very sophisticated and nasty online. Non-virgins appear to be particularly shy and elegant online.

15. Virgins like to see nude pictures on pornographic websites, while non-virgins like to read pornographic articles on pornographic websites.

16. Virgins like to go to the sexual zone, while non-virgins like to dance and write.

17. Virgins like to reply, but non-virgins will run away after reading it

Men have trouble keeping their virginity

Virgin men seem to encounter more embarrassment in marriage. Many women think that virgin men are not mature enough or cannot resist temptation. It is not easy to be a chaste man in China. Although men are not absolutely lustful as imagined, they sometimes do not want or need it, but they cannot refuse, otherwise they will be considered to have physical or mental problems. Problem, so it is extremely difficult for men to maintain their chastity in China.

But just as virgins in China are being ostracized, a trend of abstinence before marriage has been rising in American society in recent years, with more and more boys and girls vowing to start having sex only after marriage. Now, a new sexual revolution movement is emerging in the United States. If you visit an American college now, you will still meet many students watching pornographic TV programs and listening to rebellious songs, and it is they - this The leaders of the sexual revolution announced that they would remain virgins until marriage. These young people reject the "lay down and have sex" counter-trend of their parents' generation and represent a new "counter-counterculture." According to a recent study by the Centers for Disease Control and Prevention, the number of high school students who have not had sex increased by 10% from 1991 to 2001.

In fact, whether to be a virgin or not is essentially a person's belief. When people live in this world, they must have some ideas and beliefs. When others agree with you, you can be happy and contented; when others oppose you, you should be happy and contented even more, and stick to your beliefs without hesitation. Otherwise, a lot of hard things will be missing from people's hearts, and even a quarter of an hour of joy can't save anything. Of course, our society must also be tolerant. Since we tolerate premarital sex, why do we make it difficult for "virgins" who insist on chastity before marriage?

Things a virgin should pay attention to when having sex for the first time:

Men are more nervous than women when having sex for the first time.

Remember to shower, change clothes, and brush your teeth, and don’t rush to leave a bad impression.

Don't forget to brush your teeth when taking a shower; don't take any leftover dirt with you to bed after the wedding. You can also spray some oral fragrance to avoid bad breath.

Don’t forget to update your underwear: Don’t think that you are about to get married, so you only wear a bath towel or bathrobe. This approach is too impatient and should be avoided; you should still wear underwear, so that you can also enjoy undressing during the process. pleasure.

Don’t take your bath too short: Don’t be too hasty and try to get out of the bath as soon as possible. Because when men take a bath, women have a lot of preparation work, such as removing makeup, preparing bedding or contraceptive items, etc.

A considerate man can prepare his newlywed wife for the bath after bathing, such as filling the bathtub with water, putting away towels, bath towels, and toothbrushes, etc. When a woman takes a bath, please leave more time for her to prepare, comb, and maintain her body in the bathroom.

You can also prepare some late-night snacks to ease the atmosphere, relax the tension during the wedding, and clear your mind a little bit.

The most important thing is that during the whole process, it is best to avoid having relatives and friends make trouble at the wedding, because this is your most beautiful and most anticipated moment, and you should cherish it.

It's best to let your partner go to bed first. Men can use some reasons to avoid it, such as going to the bathroom, etc. It is polite to let the woman go to bed first to prevent her from feeling shy, and then the man lies quietly on her right side. Men should avoid going to bed first and then urging women to go to bed. This semi-command tone will leave a bad impression on the woman.
