Two years ago, my husband and I gradually stopped having sex. But my body had matured, and I constantly harbored intense desires. I couldn't focus on housework, and found myself thinking about cheating and other lewd acts. When I confessed these feelings to my husband, he agreed to fulfill my wish, saying, "This is only once." However, our act was seen by our son. He looked down on me, but the next day appeared in the bedroom wearing handcuffs.
