I have played sports my whole life, plus went to an all girls catholic school and was never weird about changing in public. I wouldn't want someone coming up to me trying to have a 10 min conversation in the locker room though.
And Mike you are dead on about being married. More people have hit on me knowing full well that I am married. And even seeing my husband with me doesn't stop them. I don't mind flirting but I'm not going home with you buddy!
I was in a bar once though and in the bathroom there were a group of women trying to all take their wedding rings off since they were out on the town having Girls Night Out.
