Having sex is a perfectly normal thing between couples, but there are some situations where it is not suitable to have sex, and everyone should be aware of these.
1. When the body is very tired

Many busy office workers "insist" on having sex at night despite being exhausted. Traditional Chinese medicine believes that this damages vital energy and harms the kidneys. Moreover, a tired body makes it difficult to reach its optimal state, making orgasm almost unattainable. If both partners experience physical and psychological fatigue due to exhaustion, they may even develop feelings of reluctance and aversion, which, over time, could lead to frigidity in some sensitive individuals.
It's recommended to get some sleep and rest before having sex; or place two pieces of chewing gum by your bedside and try the already popular "morning sex" the next morning. Don't worry about being exhausted the next day; the German women's football coach has confirmed that morning sex keeps the players energized all day.
2. When you are very full
It is crucial to remember never to have sex on a full stomach. Otherwise, the sexual organs, brain, and other organs will compete with the stomach and intestines for blood supply, leading not only to indigestion but also to systemic blood circulation disorders. People often experience lower back and hip pain, and those with weaker stamina may even experience dizziness and nausea. Vigorous movements may also trigger acute appendicitis.
3. When drunk

Alcohol may seem to enhance sexual function, but it actually impairs it. Traditional Chinese medicine has long held that sexual activity after drinking depletes vital energy and damages essence. While alcohol temporarily increases the excitability of the brain's nervous system, it temporarily reduces sexual function. Women may experience ovarian dysfunction, affecting normal ovulation; men may experience erectile dysfunction or shorter duration of intercourse. Sexual activity after drinking can also increase testosterone-binding globulin levels in men, damaging the testes and weakening their ability to produce testosterone (a sex hormone). Furthermore, 70% of sperm may be underdeveloped after drinking; if conception occurs under these circumstances, 26% of the fetus will have health problems, especially intellectual disabilities.
4. Right after taking a hot shower
Before engaging in sexual activity, taking a clean and hygienic shower is certainly acceptable. However, many people use a long, intimate bath together as foreplay. In reality, a hot bath exceeding five minutes depletes a significant amount of energy, and since sex requires sufficient energy reserves, the duration of intercourse is often shortened under these conditions. Furthermore, as the body relaxes under the influence of hot water, entering a resting state, organs are less likely to become quickly aroused. Vigorous intercourse can cause rapid congestion and damage to the sexual organs, and rapid pulling movements can easily injure muscle fibers. Most importantly, a prolonged hot bath reduces sensitivity, especially in women, making it significantly more difficult to reach orgasm.
If you're cleaning yourself before sex, please keep it under 5 minutes; if you want to enjoy a romantic bath together, save your intimate time for after sex.
5. After an argument

As the saying goes, "quarrels at the head of the bed are reconciled at the foot of the bed," meaning that couples often resolve their emotional conflicts through physical intimacy after an argument. However, after an argument, the body is filled with the seven emotions of joy, anger, worry, thought, grief, fear, and shock. At this time, the body's Qi and blood circulation is disordered and stagnant, and vital energy is blocked. If sex is performed under such circumstances, it will exacerbate the abnormal circulation of Qi and blood, creating various health risks. Especially when one partner is in a bad mood, forcing sex is more likely to generate negative emotions and backfire.
6. After watching an erotic film
Some people enjoy using erotic films to enhance their experience, but research has found that increasingly erotic visual stimulation causes extreme excitement in the human nervous system. During sex under such high stimulation, the brain often experiences oxygen deprivation. While temporary brain hypoxia may enhance the dreamlike sexual pleasure for some, prolonged oxygen deprivation exceeding physiological limits can lead to dizziness and weakness. These symptoms should not be mistaken for normal aftermath of intense sex; they are actually manifestations of autonomic nervous system dysfunction. Over time, this can damage heart and brain function.
