An interesting study conducted by the Department of Psychology at UCLA has revealed that the kind of face a woman finds attractive on a man can differ depending on where she is in her menstrual cycle.
The study revealed that while a woman is ovulating, she tends to be attracted to men with rugged and masculine features.
However, when she is menstruating she tends to prefer looking at a man with a knife lodged in his temple and a bat jammed up his arse while he is on fire.
Further studies are not planned.
