Scientists link biological responses during sex to a person's neurological type. People's sexual behavior types are divided according to the type of reactive behavior and individual differences: such as adhesive type and agitated type. Some people are in an excited plateau state as soon as they enter the state.

Excitable people are more excited during sex; inhibited people are more clingy. In addition, the intensity of various physiological reactions in sexual life is determined based on the reaction of people's autonomic nerve function. According to the physiological laws of sexual response, emotional excitement will inevitably occur during sexual intercourse, such as accelerated heartbeat, rapid breathing, muscle contracture, flushed skin, increased blood pressure, etc. The sweat gland system also responds. However, the intensity of this hyperactivity is determined by the above-mentioned nerve types and autonomic nerve function.

Therefore, the strength of the reaction cannot be explained solely by the physical reality. A young man with a great body may sweat during the entire sexual activity because he is agitated and his autonomic nervous system is so flexible and sensitive. But people with adhesive type rarely sweat or only sweat slightly.

There are generally two explanations for the phenomenon of profuse sweating:

The first is physical problems, such as being weak, sick, malnourished, and sweating profusely even if it is not sexual intercourse. . This phenomenon fully reflects its neurological dysfunction and inability to support the balance and coordination of physiological state.

The second is psychological problems, which are common in situations of excitement, tension, fear, and worry. It is particularly worth mentioning that those who have sexual dysfunction, such as impotence and premature ejaculation, have uncontrollable anxiety whenever they have sex, worrying that the penis cannot erect, or fearing early ejaculation. Due to excessive mental stress, sexual excitement cannot be concentrated locally, but spreads to the whole body, which will inevitably lead to sweating. Just like some people who fail to succeed in on-the-spot exams or in labor, work, or experiments, they are so anxious that they sweat profusely. They are definitely not physically weak, but purely the result of psychological tension and stress.
