A fresh way to practice sex skills (adult novel about sex knowledge)

When a man is having sexual intercourse, his waist, back, shoulders and arms play a very important role, because these parts of the body are the main force points in the intercourse between men and women. Therefore, if men want to have a smooth and comfortable "performance" during sexual intercourse, they should pay attention to the health care and motor function of the above-mentioned limbs on a daily basis. If you want to keep the motor function of these parts smooth, it is best to do more targeted exercises that help these parts in your spare time. The following is a simple soft exercise.
