Do men find all other men a threat, when it comes to the woman they like? I was out with my best friend last night who is gay, a girl we both were good friends with in high school and her friend she met at college. Her friend obviously liked her and even though he knew my best friend was gay he still acted like he was a threat. This isn't the first example I've experienced. Do straight guys feel threatened by their girlfriend's gay male friends? Even though there isn't a logical reason to do so?
