Your wife has been chronically sick. You love her dearly and the though of losing her is beyond anything you could possibly imagine. Because she has been sick, you have not been able to have meaningful sex for months. You try not to care about it and you don't want to care about it, but you can't help it. Carynn is your wife's close friend from grade school and they've been friends for decades. She is married but she, too, has challenges with her husband. Carynn is a nurse and she comes over often to take care of your wife and to check up on you. You and Carynn would never, ever want to betray friendship or the boundaries of marriage. You spend a lot of time together and get to know each other rather well. Carynn arrives with dinner and her medical bag. You show her in to the house. Hi Carynn, great to see you as always. Thanks for coming over.
