These behaviors between couples can be classified into levels

Foreplay is the prelude to sex. Correct foreplay can not only fully ignite the desire of both parties, but also stimulate orgasm, achieving twice the result with half the effort. But many of the habits we take for granted are harmful or even dangerous to sex.

Next, let’s rank some dangerous behaviors according to their severity.

Five-star:

Drinking alcohol can help with sexual performance, and taking a hot bath can help. Many people like to have a few drinks before passion, thinking that this will "raise their morale". But a little wine can make you happy, but too much can ruin your character. Although you can be emotionally excited and enthusiastic about preparing to start after drinking, your body can easily stop working, and the prelude that you have worked so hard on will end up in a deep sleep or a hasty conclusion. Some people are accustomed to taking a hot bath as a way to relax before sex, especially when two people take a bath together, which can create a good foreplay atmosphere. However, it is best not to take a hot bath for more than 5 minutes, because hot baths will consume a lot of physical energy, and as a result, it is easy to "withdraw" quickly when the actual game comes.

Four-star:

Have a big meal. Having a romantic candlelight dinner before the drums start to beat seems to set the mood and reserve sufficient fighting power. But this self-righteous behavior can sometimes derail the entire romantic plan. After a full meal, most people will feel groggy and many people will even feel sleepy. This is because after a meal, your gastrointestinal tract is competing with your brain and "combat organs" for blood, so your sexual interest will inevitably be reduced.

Three-star:

Extreme mood swings, such as extreme joy and sorrow. It is said that couples do not hold grudges overnight. After a quarrel, the conflict can be resolved through sex, a dual psychological and physiological exchange. However, traditional Chinese medicine believes that when one's emotions change extremely, the circulation of qi and blood in the body is in a state of disorder and stagnation, so sexual intercourse is not advisable. If both parties or one of them is reluctant to have sex at this time, it is easy to generate rebellious and disgusted emotions, which will lay hidden dangers for the future married life.

2-star:

High physical labor or play. The "honeymoon" is a torture for some people. After the wedding banquet, people start sightseeing without taking a rest. At this time, the body is easily fatigued. If they force themselves to go on, even if they start having sex, they will not be able to reach orgasm due to limited sexual arousal. At the same time, if you work hard or do heavy physical work during the day, don't try to overdo it at night.

One star:

Watch erotic movies or read erotic books. Erotica isn’t for everyone. On the one hand, too much stimulation can lead to "sexual fatigue", which means a lack of interest in reality; on the other hand, due to the exaggerated messages conveyed by erotic films, watching too many of them can cause people to have incorrect expectations, making sex imperfect.
