Why does religion advocate abstinence?

Sex is normal, but sexual desire is like drug addiction. Drug addicts will lose control. The essence of religious doctrine is that self-cultivation and practice are consistent. If a person craves sexual desire and indulges in it, it will harm his health. If you hurt yourself, you will be hurt. Androgyny. Therefore, Taoism and Buddhism prohibit the sexual desire of believers. Taoist practice emphasizes refining gas, refining gas, refining spirit, refining spirit into emptiness, and refining emptiness into harmony. The essence of Taoism is innate essence, not acquired essence, but acquired essence transformed from innate essence. Lust damages the acquired semen and the innate essence. So religion emphasizes abstinence. This desire contains many desires. Not just sexual desire.
