The second is exercise.

Moderate exercise is also a good way to improve sexual ability. For some young white-collar workers, instead of sitting in the office all day, it is better to have more activities in the middle. For middle-aged and elderly people with plenty of time, they can do more jogging, walking, swimming and other sports, but the amount of exercise should not be too large. Once they feel tired, they should stop exercising at once.

The third is the law of sex.

On the law of husband and wife's life. In other words, no matter how busy the husband and wife are and how often they travel, they must ensure a regular and moderate sex life. If you don't have sex for a long time, your ability will naturally decline. In addition, in sexual life, both husband and wife must keep a relaxed attitude and don't take sex as a task. The taste of mountains and seas will answer you.
