That to many men there are two types of women - the ones you find attractive and have potential with and the types that aren't. And, if your male friends talk often about the women in the first category in your presence, they are indirectly telling you that you are in the second category.
Happy to be told iabu but interested in testing this theory as have noticed a real upswing in conversation about how good looking various women are when I am with them which leaves me feeling quite bad about myself.
I am not going to be spending time with these people anymore and am otherwise fairly resilient but interested in views nonetheless
