We have been married 38 years and our sex life has varied from often to occasionally. I recently retired and have been having sex weekly. I’m ok with that but she says it’s not fair that her two sisters aren’t having sex and she is. One sister lost her husband from a car accident that lead to his early demise, the other has had lots of heath issues and has lost interest in sex. Now as unfortunate as that is, I do not believe it should have any effect on our life, especially sex.. My wife has had her own health issues ( breast cancer survivor) and the usual age health issues, blood pressure etc. but even with that she is in good health and a beautiful lady.. I reassure her always but she still struggles with sex.. what’s up?
