Everyone knows that foreplay is very important for the subsequent sex. So you know, some foreplay can be harmful!

Three types of foreplay that harm your health:

1. Alcohol

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. Men have difficulty in erecting or their duration of erection is shortened. 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 it is champagne, strong liquor, draft beer, or wine that has always been labeled as healthy, abstain from sex for 2 hours after drinking.

2. Hot water bath

Many people regard bathing together 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. Most importantly, long hot baths reduce body sensitivity.

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.

3. Movies

The latest research has found that the more fragrant visual stimulation makes the human nervous system extremely excited, and 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.

Tip: You might as well use more "natural" stimulations such as touching and kissing to stimulate lust.

The 7 best periods for sex

1. The night before an important report

Sex relieves tension, lowers blood pressure and reduces stress. One study found that having sex before public speaking, major exams, or negotiations can make people more focused and proactive, reduce stress, and increase success rates.

The human body mechanism is suitable for having sex in the morning. Sexology expert Dr. Jessica O'Reilly said: "Not only are testosterone and energy levels highest in the morning, but oxytocin levels rise after sex, making the couple bonded throughout the day, and dopamine levels rise, which makes people feel good. . ” So it’s really nice to start the day with a good night of sex.

5. After exercise

You must take advantage of the good opportunity to feel high after exercising, and exercise can make human nature perform better. A study conducted by the University of Texas at Austin in the United States used pornographic materials to compare and analyze the reactions of women after a 20-minute bicycle ride. It was found that blood flow to their reproductive organs increased by 169% after exercise. Moreover, after exercise, the body image is better and people are more confident in their figure, so the suppressed sexual impulse will burst out. Exercise can also secrete more testosterone, which is a very important sex hormone and can make people's desire stronger.

6. After a bad day

Want to get rid of the stress caused by a busy day at work? Sex is a healthier way to relieve stress than a few beers. "Multiple studies have shown that having sex and other acts of physical intimacy, even holding hands, can significantly improve your mood and reduce stress in the days ahead," says Dr. O'Reilly. In addition, exercising in bed to push away tension and frustration can help People are more passionate and enthusiastic. O'Reilly says that even if your bad mood is caused by your partner, a passionate sex session can help resolve the issues between you.

7. Just did something “terrible”. Another great time to have sex is right after a frightening experience, such as riding a roller coaster or watching a horror movie. Dr. O'Reilly said: "When adrenaline begins to secrete in large amounts, the human body is actually in a state of arousal. In this case, people's sexual response will increase to a higher level."
