Re: Dating
I beg to differ on this one, during college and early years of my work life I was this guy and one of the main reasons of girls being around me was respect, i looked at them respectfully and thus they were comfortable to talk to me, and not to mention I did date 2 of the women in the group.
And thus PCG talking to girls or being part of a co-gender group gives you a certain comfort level to talk to your opposite sex.
