Yes men can get stupid around very attractive women but we won’t tolerate it forever. We are also more thoughtful about how we treat women we are not interested in. We are less likely to take advantage of these women (if they like us) than vice versa.
Also I am not just talking about physical looks for who women get strongly influenced by emotion. I am also talking about guys who might have attractive personalities (funny guys) but can be cómplete D bags in other aspect. Women seem to get intertwine emotion and respect for those guys. They make excuses for their shortcomings.
