The More Women Want Sex The Higher Their Standards 

The more women want sex, the more they up their standards when choosing a short-term mate.Researchers found that this is in direct contrast to statistics for men, after they study revealed that men are more likely to lower their standards the more "sexually hyperactive" they become.

Ovulation Leads Women to Perceive Sexy Cads as Good Dads 

Women choose bad boys because their hormones make them, new research suggests. When ovulating a woman's hormones influence who she sees as good potential fathers, and they specifically pick sexier men over obviously more dependable men.
"Under the hormonal influence of ovulation, women delude themselves into thinking that the sexy bad boys will become devoted partners and better dads," Durante said. "When looking at the sexy cad through ovulation goggles, Mr. Wrong looked exactly like Mr. Right."
"When asked about what kind of father the sexy bad boy would make if he were to have children with another woman, women were quick to point out the bad boy's shortcomings," said Durante. "But when it came to their own child, ovulating women believed that the charismatic and adventurous cad would be a great father to their kids."
"While this psychological distortion could be setting some women up to choose partners who are better suited to be short-term mates, missing a mating opportunity with a sexy cad might be too costly for some women to pass up," said Durante. "After all, you never know if he could be the 'one.'"
