The topic originator must have a difficult time watching Base Ball games on TV. The players are always adjusting.
As for my self, I adjust when I need to and I have no concern about the orientation of any guys that may view me.
A normal procedure.
Now, when out in public with a mixed group, i. e. boys and girls and yes children I attempt to be discreet.
Admittedly, this is an interesting topic, just as when a group of people are talking about crime. I am sure that a criminal hearing the conversation would think that everything is talking about him/her.
Of course that is not the case, but the case of "If the shoe fits, wear it" could be applied here.
