Our sexual fantasies increase

A new study done at the University of Lethbridge in Canada found that during the three days surrounding ovulation, heterosexual women had an increase in the frequency of their sexual fantasies -- aka got really horny. But not only were we horny, our fantasies became more "arousing" and featured more leading male characters. Another surprising finding was that we became more "femalelike" in our fantasies, focusing on emotions and feelings rather than the actual sex acts. [Live Science]
