Everything must be conditional, and sex is a process of normal functioning of a personality, and it is also a situation that must be explained. If both the psychology and psychological state are normal, the following other conditions must also be met.
Neurohealth system
The central nervous system is first composed of the cerebral cortex, hypothalamus, and spinal cord, followed by peripheral nerves that control various personality organs. The central competent authority is responsible for command functions, while the peripheral nerves are responsible for the work of the "second hand", transmitting sexual stimulation from the sexual organs to the central competent authority, and also transmitting instructions from the central nervous system regarding sexual activity to the sexual organs.
Adequate sex hormones
The male body is mainly composed of androgens, represented by testosterone. The female body is mainly composed of estrogen, which is represented by estradiol. Sex hormones can not only express a person's sexual characteristics, such as a strong personality, tall figure, clusters of beard and hair in men, delicate skin in women, plump breasts, etc., but also induce, drive, and maintain sufficient sexual desire, helping sexual impulses enter orgasm, and other functions. Sex hormones are an important 'driving force' for sexual function.
Essential sexual stimulation
Heterosexual stimuli from different sources such as visual, auditory, tactile, and olfactory stimuli, as well as stimuli from spontaneous color fantasies, can cause strong sexual stimulus responses. Especially when stimulating each other's sensitive parts, the effect is more significant. This type of tactile sensitive area includes: Zone A: male and female have the highest level of sexual sensitivity, with a slightly lower level of sexual sensitivity than Zone B: nipple, inner thigh.
