Sexual life is an important part of married life. A harmonious sexual relationship is a natural physiological need for both men and women, and it's a common aspiration for both partners in a marriage. Both parties have the obligation to cooperate closely, and both have the right to be satisfied. In the process of sexual activity, from the arousal of sexual excitement to emotional communication, from the investment of both parties' body and mind to jointly reaching a sexual climax, there are significant psychological factors involved.
