Premature ejaculation is a condition in which ejaculation occurs before the penis enters the vagina or just inside the vagina. On average, Chinese men are not considered to have premature ejaculation if it takes more than two minutes. Premature ejaculation is a condition caused by high penile sensitivity or insufficient erection of the penis. It is normal for men to experience physiological premature ejaculation the first time they have sex, without experiencing external stimulation, and the ejaculation symptoms occur when they are in a more exciting situation. But if frequent early ejaculation without getting pleasure should be suspected as pathological premature ejaculation. In addition, premature ejaculation symptoms may occur when the foreskin is too long and the glans surface is subjected to less friction in daily life and has relatively high sensitivity. And when men have a deficiency of kidney yang or excessive psychological stress, a decrease in the degree of penile erection may also trigger the occurrence of premature ejaculation. In conclusion, it is recommended that patients should not worry too much about premature ejaculation, adjust their mindset and seek help from a doctor at a local regular hospital in time, but do not use drugs blindly to avoid affecting their health.
