Normal sexual life is generally based on the principle that there will be no obvious fatigue, listlessness, backache and fatigue on the second day of sexual life, and it will not affect work and study. If there is discomfort, it may suggest that life is too frequent. Frequent sexual life may cause erectile dysfunction, premature ejaculation, oligospermia and emaciation. Generally speaking, young people before the age of 30 will have 2-4 times a week. I suggest you make reasonable arrangements.
