"They recruited 71 sexually active, heterosexual women, ages 18 to 48"

I wonder how long this took, impressive so far, regardless.

"According to the scientists, promoting male self-esteem “may strengthen the pair bond,"" etc.

I'm not so sure these are the most advanced scientists if it took them until 2012 to figure out something which has been constant since prehistoric times. It's not so difficult that a cave man or cave woman couldn't do it.

From now on, whenever I have sex with a Barbary macaque, I'm going to feel like I'm being manipulated...
