Since the dawn of time when females of most land species go into heat, they literally get hot. Their genitals inflame, swelling with blood, and give off an odor that attracts a mate.
You, as a male (most likely or this would probably be in /u/), have been given this instinct through millions of years of genetic handing down of finding a female that is ready to mate and pass on your genetics to further the race.
Hope this helps.
