Normal ejaculation is a complex physiological process involving the nervous system, the endocrine system and the urogenital system, and if any of these links becomes functionally or organically impaired, it can lead to non-ejaculation. Let us first introduce the conditioned reflex. Pavlov, a Russian physiologist, conducted an interesting experiment in which he found that every time he gave a dog meat, the dog would drool, which is a basic physiological reaction of the dog and indicates that the dog is healthy. Thereafter, he always pressed the buzzer before each time he gave the dog meat. When trained many times, the sound would make the dog drool like seeing meat as well, even if no meat appeared after the buzzer sounded. Then analogy to the ejaculation process, if in a certain situation may ejaculate, for this situation to strengthen, then there is a good hope to solve the ejaculation problem. The specific need to choose props or methods that are similar to the stimulation sensation according to the individual situation, if you can induce ejaculation, then articulate with sexual life, and slowly form a normal ejaculation reflex. The conditioned reflex training method is more effective for non-ejaculation caused by masturbation habits. This kind of non-ejaculation is mainly due to the fact that the intensity of sexual stimulation during masturbation far exceeds the intensity during intercourse, and when the ejaculatory center is accustomed to the strong stimulation of masturbation and fails to reach the accustomed ejaculatory threshold during intercourse, then it is unable to complete the action of ejaculation. The most commonly used instrument is the electric massager, which produces vibratory stimulation by mechanical vibration, which is the most versatile method of stimulation. The trigger point for masturbation induced ejaculation varies from person to person. If the focus is on penile body stimulation, try changing the position and angle of intercourse; if the focus is on stimulating the glans tether, you can use your hand to assist in tightening the local skin; if the focus is on speed and friction, you need to improve your physical ability and waist and abdominal strength, and also ask your spouse to cooperate with the relative movement. The problem of non-ejaculation can be solved by understanding the intrinsic nature of the stimulation point of the method, by adjusting the sexual lifestyle and learning the skills, and even by replacing the original habit with some adult products. The simple principle is: find the stimulation conditions, understand what they are, find similar stimulation conditions in sexual life, and replace the original stimulation conditions. The process of treatment requires the strong cooperation of the spouse. Also using a hot water sitz bath before intercourse to warm the perineum and stimulate it also helps the penis to become erect, increases libido and promotes ejaculation. Finally it is important to realize that habits (conditioned reflexes) take time to develop and change, and it is very important to develop a complete training program and to stick to it.
