For whatever reason, my wife has had a sudden increase in her sex drive. She is like an 18 year old boy, thinking about sex every 30 seconds. It’s not a problem as much as a curiosity. We have been married for 25 years and all these years I have been more interested in sex that she has, but she has always been willing. Now she is the aggressor and wants sex once a day instead of our typical once a week (not that we do it that often). My question is why? The doctor says she is nowhere near being pre-menopausal and she 10 years beyond the typical sexual peak for women, so what is it?
