These studies, some involving hundreds of people, found that a woman’s attractiveness fluctuates depending on where she is in her menstrual cycle. Women’s faces and voices change over the menstrual cycle. The hormonal shifts cause facial and vocal changes in women are at their most alluring near ovulation, when they are most fertile.
One study, which published its finding in the journal Hormones and Behaviour, took more than 200 photographs of women’s faces at two separate points in their cycle. Also, their speaking voice were recorded at both times and their hormone levels taken. Then they got over 500 men to rate the pictures and voice samples. Not surprisingly, it was found women were at their most appealing when "near ovulation when fertility is highest." A group of more than 500 women were also asked to rate the photographs based on flirtatiousness and attractiveness to men and the subjects scored higher when they were most fertile.
And how do researchers explain that both men and women perceive these hormonal changes as changes in attractiveness? One reason could be caused by blood flow changes that affect facial color, changes to acne or puffiness caused by water retention.
I may be only a simple-minded bimbo, but the answer seems kind of clear to me: when women are fertile, they get horny and people are attracted to horny people. When you are horny, you tend to try to make yourself more attractive so you can attract a mate. perhaps you put on more jewelry, wear clothing that is a bit more flashy or revealing, or show a little more skin...
Well then... if women tend to "dress up' when horny, that would explain why sissies always adore dressing up -- because they are always horny!
