If your old lady is younger than about 53 or so, you might hear that statement many times over a two week span of time during a month. For women its an increase in Estrogen production to facilitate getting pregnant. For men this situation happens twice a year. As the Testosterone production drops after the normal mammal mating seasons. In us canines its late fall, to mid winter and mid Spring. Its in this time that us wolvez are ready to produce seed to create wolf-pups, for human men its the time , in fact prime time for mating. Once the natural mating season is done, the male juices are reduced and as such a slight decrease in ambition, and desire are also reduced. The senses are numbed and as such the male period begins, which usually lasts about 2-1/2 weeks. So as would a wolf squirting on a tree, I’m marking territory, and howling, this is my 2-1/2 weeks.
