We don’t really know what determines sexual desire. Of course, hormones… and all sorts of psychological, social, environmental, etc. circumstances. In fact, we don’t even know how to measure it exactly. What do we measure a lot and a little against? Age? Would you have thought that it’s not women in their twenties who think about sex the most? Of course: women between the ages of 27 and 45 fantasize more often and get into bed with their partners sooner than their younger and older counterparts. But in addition to age and hormones, such prosaic reasons as stress, excess weight, smoking, certain diseases, and medications can also reduce libido. Perhaps not surprisingly: the most common cause of low sexual desire is a deterioration in the quality of the relationship. <\/p>\n
