It is not possible to generalize whether 3 times sex in 1 month is normal or not. There are individual differences in each person’s sex life, and it is also related to the age group. 3 times sex in 1 month is normal if you don’t feel tired, the man doesn’t have any obvious spermatozoa, and the woman doesn’t masturbate. between the ages of 25-35 years old, sex will be more frequent, and it can be 2-3 times per week. between the ages of 35-45 years old, it will be less frequent, and it can be 1 time per week. over the age of 45 years old, sex can be 1 time per month and a half, and it can also be 1 month 3 times sexual life. Because of the physiological needs of normal people, it should be a slow process of decline. Physiological needs decline with the body’s hormone secretion is reduced, but also with the growth of age, the increase in human affairs, will gradually shift the attention of the mind to other places.
