6 "dangerous preludes" that require you to be more vigilant. Category A includes three types that everyone originally thought could promote sex, but unexpectedly destroyed the quality of sex; category B includes three types that everyone has become accustomed to, but in fact also destroy the quality of sex.

Category A dangerous prelude

So far, no one has prepared a sex hormone injection. I heard that fine wine, romantic double baths, and erotic movies can stimulate the secretion of sex hormones, so many people use it They are used to create an atmosphere of lovemaking, but everyone knows...

Dangerous Prelude 1: Alcohol Danger Index: ★★★★★

I don’t know if it really comes from ancient customs, or which director had a brilliant idea Modern romantic fiction, in short, alcohol has become a common erotic stimulant in movies. Shakespeare was the first to point out that "wine stimulates passion, but makes action in vain." It is true that alcohol appears to help one's nature, but in fact it destroys one's nature. Traditional Chinese medicine has believed since ancient times that having sex after drinking consumes qi and damages essence. Although the excitability of the brain nervous system is temporarily enhanced after drinking alcohol, sexual function is temporarily reduced. Women may have ovarian dysfunction, affecting normal ovulation; men may have difficulty erecting or shortening their duration. Drunk sex can also increase testicular binding globulin in men, damage the testicles and weaken their ability to produce testosterone (sex hormone). In addition, 70% of the sperm produced after drinking may be underdeveloped. If pregnant under such circumstances, 26% of the fetuses will have health problems, especially intellectual disability.

Tips: Whether you choose imported champagne, strong liquor, popular draft beer, or wine that has always been labeled with health labels, abstain from sex for 2 hours after drinking.

Danger prelude 2: Hot water bath hazard index: ★★★★

It’s certainly understandable to be clean, hygienic, and take a shower before having sex, but many people regard bathing together for tens of minutes as a prelude to sex. In fact, a hot bath for more than 5 minutes consumes a lot of physical energy, and sex requires sufficient physical energy reserves. In this case, the duration of sex is often shortened. At the same time, the human body gradually relaxes under the action of hot water, and the whole body enters a resting state. It is difficult for various organs to be excited quickly. Intense sex will cause rapid congestion and damage to sexual organs, and rapid stretching can easily damage muscle fibers. The most important thing is that a long hot bath will reduce the sensitivity of the human body, especially the sensitivity of the female sexual organs. At this time, it will be even more difficult to reach orgasm.

Tips: If you do body cleaning before sex, please limit the time to less than 5 minutes; if you want to enjoy a romantic double bath, please move the lingering time to after sex.

Dangerous prelude 3: Erotic movie risk index: ★★

If we trace the origin, one of the reasons why erotic movies appear is to increase the content of sex hormones in the body before sex. A few percentage points. But the latest research has found that increasingly fragrant visual stimulation makes the human nervous system extremely excited. When having sex under such high stimulation, the brain is often in a state of hypoxia. Although temporary brain hypoxia can add fantastic sexual pleasure to some people, over time, when brain hypoxia exceeds physiological limits, people will feel dizzy and collapsed. Do not regard these symptoms as symptoms of intense sex. Normally, they are actually manifestations of out-of-control autonomic nerves in the human body. In the long run, heart and brain functions will be damaged.

Tips: You might as well use more "natural" stimulations such as touching and kissing to stimulate lust, and of course your love words.

Category B dangerous prelude

Some people regard sex as a way to reconcile after a quarrel; some people still "persist to the end" even if they are deeply tired; some people are used to having passion after a meal, but they don't know...

Prelude 4: Quarrel Risk Index ：★★★★

As the saying goes, "A quarrel at the head of the bed ends with a fight at the end of the bed." After a quarrel, men and women often use physical tenderness to resolve emotional conflicts. But after a quarrel, the seven emotions of happiness, anger, worry, thought, sadness, fear, and surprise are prevalent in the human body. At this time, the flow of Qi and blood in the body is in a state of chaos and stasis, and the essence and Qi are blocked. If you have sex under such circumstances, It will aggravate the irregular operation of qi and blood, burying various health risks. Especially when one of the parties is still in a bad mood, forcing sex is more likely to produce resentment and be counterproductive.

Tips: Even if you have forgiven each other after a quarrel, you should wait until the emotions have completely calmed down.

Prelude 5: Fatigue risk index: ★★★★

Many busy office workers “persist” in having sex at night despite being exhausted. Traditional Chinese medicine believes that this will damage the essence and harm the kidneys. Moreover, it is difficult for a tired body to reach its optimal state, and orgasm has almost become an elusive thing. If both parties suffer from physical and psychological fatigue due to lack of physical strength, they may even experience fear of difficulties and boredom. In the long run, this may lead to sexual frigidity in some sensitive people.

Tips: Get some sleep first and have enough rest before having sex; or put two pieces of chewing gum on the bedside and try the already popular "morning first sex" when you get up the next day. Don't worry about being exhausted for the rest of the day. The coach of the German women's football team confirmed that sex in the morning can keep the female players energized throughout the day.

Prelude 6: Big meal risk index: ★★★

Even if the big meal is an aphrodisiac food that will make you "sex" high, you should not eat it when you are full. Otherwise, the sexual organs, brain, etc. will compete with the gastrointestinal tract for blood supply, which will not only cause indigestion, but also cause systemic blood circulation disorders. People often feel soreness in the waist and hips, and those with poor physical strength may even experience symptoms such as dizziness and nausea. Intense exercise Movement may also trigger acute appendicitis.

Tips: Wait at least 40 minutes after eating until the stomach is basically empty.
