Masturbation is a strong and somewhat rough stimulation of the genital organs, men to obtain ejaculation, women to obtain the pleasure of erotic orgasm for the purpose. Sexual organs to induce erotic orgasm is the result of the combined effect of temperature, touch, pressure and vibration sensation and other sensory functions, these senses have a certain “threshold” in receiving local sexual stimulation. The local stimulation of the sexual organs during masturbation is stronger than the local stimulation during intercourse, and after frequent masturbation the sexual organs are accustomed to excitement under strong stimulation, which invariably raises the stimulation “threshold” of various sensory functions, and when having normal sex, the local sexual stimulation may not reach the strong degree of masturbation, and the sensations of these sexual organs have been subjected to The strong stimulation of the exercise, for the smaller degree of stimulation will not work. These phenomena occur in men who are prone to non-ejaculation during sexual intercourse, and in women who suffer from a lack of orgasmic pleasure during sexual intercourse. (2) induce sterile prostatitis in men or pelvic blood stasis in women. In the period before and after masturbation, the sexual organs are suddenly and heavily engorged with blood. If in men, in addition to the penis, the most congested is the prostate, frequent masturbation will lead to continuous congestion of the prostate, the incidence of aseptic prostatitis, also due to the frequent and widespread chronic congestion of the prostate and produce symptoms similar to inflammation, so back pain, frequent urination, urinary urgency, urinary bifurcation, incomplete urination, urinary weakness, dripping white at the end of urination, urinary burning, perineal discomfort, and even sleepiness, fatigue, etc. The symptoms will come one after another. If a woman masturbates frequently, the organs in the pelvis, such as the uterus, ovaries, fallopian tubes, bladder, and even the blood vessels in the pelvic wall will stasis and expand, and symptoms such as lower back pain, lower body swelling, and perineal discomfort will follow.
