Hi Paul . Welcome to PC. Is your wife on any medication? Does she have any kind of hormone problems? That would explain alot. Sometimes when women have homonal imbalances, they don't get the proper lubrication and sex can be very painful. I would have her go to a doctor and get her hormone balence checked. The best thing you can do for her is be there for her. I know it's hard on you but you may not be the reason for this at all. Keep your head up. She'll come around.
