Married for 23 years with one 21-year-old daughter who left home for work, she now lives alone with her husband. They've been sexually inactive since their child was born. Their relationship is that of ordinary dual-income coworkers—nothing particularly bad, but nothing especially good either. A year ago, immediately after being freed from child-rearing duties, her emotions surged uncontrollably. Unable to resist, she began a purely physical relationship with a male coworker, devoid of romantic feelings. Her first sex in 20 years was terrifying; her body froze up and her partner lost his erection mid-act—an utterly terrible experience. In the end, she had sex with the coworker three times over about a month. Once he started growing bored, she sought out another partner. When that one grew stale, she moved on to someone else... After all, her husband is surely playing around outside too.
