It mainly depends on which form of exercise you choose. For monks, there are three reasons for absolute abstinence:

(1), the Buddha said absolute abstinence to monks, because the fundamental idea of the Buddha is that love is the root of life and death and the greatest constraint on the world, and it must be kept away;

(2) Monks are greedy for five desires, and when they marry and have children, their main energy is dispersed. The first consideration is not how to cultivate the temple, but how to support his family.

(3) Becoming a monk abstains from sex in order to have more time to study classics, to sit still and practice ideas, and to become spiritual teachers of believers. For believers who practice at home, they can live a normal husband and wife life, but they can't mess around with men and women and put an end to prostitution.
