When Women are only being friendly,men REALLY think women want sex

This happens alot.You smile at a man, he thinks it means you want to go to bed with him. Meanwhile the woman interprets his advances as acts of friendship.Thankfully ,scientists now have an explanation for their behavior .. and it's all to do with how male brains have evolved to pick up on the wrong signals.Researcher Mons Bendixen from the Norwegian University of Science and Technology (NTNU).,said
A man's ability to reproduce is all about seizing every opportunity. He has to spend both money and time on attracting women, which still may not lead to sex.But it costs even more to not try, because then he won't be able to reproduce at all.'But that's not how it works for women,'A woman can have sex with multiple men over a short period of time without producing any more children.
So for men, it is a low-risk, potentially high-reward situation to have sex with women whenever the opportunity presents itself.

Women's psychology, meanwhile, has evolved to set the bar higher.This means they need much clearer signals before they consider sex

In a recent study at NTNU, women said that they had acted friendly towards a man and had this misinterpreted as sexual interest about 3.5 times over the past year on average.

On the flip side, scientists found that women interpret the sexual intentions of other flirtatious women in the same way as men do.
Yet when they reported what their own intentions would be if they behaved in the same way, the women said they were far less likely to have sex with a man.
