Definition and classification of male sexual dysfunction
Male sexual dysfunction is any change in any of the five stages of male sexual activity (including libido, penile erection, intercourse, ejaculation, and orgasm) that affects normal sexual life.
It manifests as abnormalities and absence of sexual physiology.
There are several classification methods: ① Classification by etiology: organic and psychological.
②According to the time of occurrence, it is divided into primary and secondary.
Primary sexual dysfunction occurs when the problem is present from the very first sexual encounter, while secondary sexual dysfunction occurs when there has been at least one orgasm before the onset of the sexual dysfunction.
③ According to the sexual process, it is divided into: sexual desire disorder, erectile dysfunction, ejaculation disorder and sexual sensation disorder.
(1) Sexual desire disorders: mainly include low libido, sexual aversion, hypersexuality and paraphilia, which can be caused by organic lesions and abnormal psychological factors.
(2) Erectile dysfunction: The most common, there are two types: ① Impotence: Now collectively referred to as erectile dysfunction (ED), which refers to the inability of a man's penis to achieve and/or maintain an erection to achieve satisfactory sexual intercourse.
It can be divided into psychological, organic, and mixed types.
② Priapism: refers to a persistent erection of the penis that is painful.
It is often caused by organic lesions.
(3) Ejaculatory disorders: Disorders that occur in the time of ejaculation, including premature ejaculation and delayed ejaculation; disorders that occur in the ejaculation process itself, such as anejaculation and retrograde ejaculation; others include frequent nocturnal emission, spermatorrhea, or seminal emission.
(4) Sexual sensory disorders: Common ones include painful intercourse, painful erection, painful ejaculation, abnormal sensation of external genitalia and decreased orgasmic sensation.

What is sexual desire?
Sexual desire refers to the desire for physical contact between opposite sexes, as well as the desire for sexual arousal and intercourse caused by various internal and external stimuli.
Sexual desire, when it reaches a certain level, will cause an erection.
Sexual desire is controlled and regulated by the central nervous system and the endocrine system. There are significant differences between individuals, and even within the same individual, it can change with various factors such as age and health status. Therefore, it is sometimes difficult to determine the boundary between normal and abnormal sexual desire.
Isolated sexual dysfunction is rare; it usually coexists with other sexual dysfunctions such as erectile dysfunction and premature ejaculation.

Symptoms of low libido
Low libido is mainly manifested as a lack of proactive sexual desire, decreased libido, and a lack of interest in sexual intercourse under any stimuli. It is a state in which sexual activity is weakened and libido is suppressed to varying degrees.
This should be distinguished from changes in libido due to age and individual differences.
In other words, besides the decline in libido due to aging, any decrease in libido that is disproportionate to age or disharmonious in normal young adults, middle-aged or elderly people is considered abnormal libido and is called low libido.
This often manifests as a lack of sexual desire regardless of how long it has been since he last had intercourse with his wife; or a complete lack of interest in intercourse, only occasionally engaging in sexual activity when his wife initiates it.
Its etiology is very complex and can be either organic or functional.
However, if a couple's sexual desires are inconsistent or their libido decreases under certain circumstances, but their libido remains normal under other circumstances, this cannot be described as low libido.

Why do people experience low libido?
It is caused by mental and psychological disorders or even abnormalities, as well as various social factors, and is mainly related to central inhibition of the brain and spinal cord dysfunction.
(1) Disharmony in daily relationships: If the relationship between spouses is not close, not harmonious, not faithful, or even hate each other, it will inevitably lead to abnormal sexual life.
Lack of communication, lack of mutual respect, emotional instability, and conflicts between couples can gradually weaken sexual attraction and ultimately lead to low libido.
Statistics from Edinburgh show that 47% of men and 68% of their spouses believe that sexual dysfunction is caused by disharmony in daily life.
(2) Inappropriate or insufficient sexual stimulation: Sufficient and appropriate sexual stimulation for an individual means that he or she can obtain enjoyment such as visual, tactile, fantasy, and consciousness and emotion.
The type of stimulation an individual requires may be related to their partner's sexual practices and masturbation habits.
If a man does not receive adequate and sufficient sexual stimulation during intercourse, he will not generate enough sexual arousal to achieve an erection.
(3) Negative sexual experiences: Attitudes toward sex are accumulated from various aspects such as cultural background, family influence, personal experience and the sexual response of one's spouse.
Religious beliefs, parents' sexual attitudes, reading sex-related books, and witnessing sexual events can all constitute a variety of sexual experiences.
Early sexual experiences seem to play an exceptionally important role for individuals. Guilt about a history of masturbation and humiliation from being mocked for early sexual behavior constitute traumatic sexual experiences that some people find difficult to overcome.
The attitudes toward sex that children experience during their development, as well as the interference in interpersonal relationships, especially family relationships, can have adverse effects on their future sexual activities.
(4) Influence of inhibitory factors: In daily life, due to the tension of work and study, or the busy social work, or the excessive mental labor, the private life of an individual is relatively inhibited, which affects the functional state of the higher nervous system, thus gradually becoming indifferent to sexual life, resulting in low libido or no libido.
Once the above-mentioned causes are resolved and physical strength is restored, libido can gradually return to normal.
Those with weak or tense mental health are more prone to anxiety and depression under the influence of external factors and the environment, resulting in complex psychological disorders that interfere with the function of the cerebral cortex and thus lead to low libido.
Excessive sadness, sorrow, anger, or strong mental stimulation can disrupt the balance of the seven emotions and six desires, making low libido more likely.
Low libido can also be caused by feelings of guilt stemming from a lack of self-confidence and insufficient understanding of sexual behavior.
In addition, excessive sexual activity, masturbation, and indulgence in pornography can lead to spinal cord central disorder over time, which can also cause low libido.
