it's still bad! Sexual life manual for married couples who have reached retirement age in the case of Shinji and Akiko KUSUNOKI

This time, I visited Mr. and Mrs. Tochigi who have reached their retirement age. In his current career, he was a salesman and his husband Shinji worked hard with no family in mind. His wife Akiko, who had reached retirement age and thought that she could finally live happily with the couple, but her husband, who didn't have a lot of hobbies, sent him every day as if he were out of his mind. Even if his wife asks, his husband treats him as an intruder without motivation. Is my husband no longer interested in his wife or sex?
