My wife of 21 years has no sex drive. It has been seven months since we last had sex. Previous breaks have been up to a year. These might be interrupted by a one-off encounter or a week of almost daily occurrences. I have been faithful to her since we became exclusive; I assume the same for her.
We are both healthy and fit for our ages (mid 40s), and have two children. Her sex drive started to wane after a gynaecological surgery. In contrast, my sex drive is as high as ever. I’ve always tried to be conscious of her needs and made a significant effort for her to achieve orgasm.
