I hold doors for anyone no matter what their sex, its just politeness.
You don't strike me as the type of person to actually think something like that would make you gay Beowulf, so I'm kinda confused what point you were trying to make with this topic 
There was no point. It was just a question.
I think. I can't remember.
It was just an inane question about social etiquette that popped into my mind while at work.
I think I should have asked, "is it emasculating ...?"
I should expand on this ...
Now, if you see someone 20 yards behind you holding a drink, you might feel obliged to hold the door open for them while you wait for them to catch you up, whereas you might not if they were not holding a drink.
So, if the person behind you has their hands free, then there is probably some distance beyond which it becomes more sensible to let the door swing (or slam) than to stand there holding it. I know that often if I am the person several yards behind, I feel compelled to jog lightly to catch up the person in front in order help the person in front make up their mind, and to make sure that they are not left standing there holding the door beyond a sensible number of seconds.
This sensible distance might be greater for a woman than for a man. If you decide to hold a door open for a man who is, say, 20 yards behind you, he might think, "I can open the bloody door myself, you know".
Ah well, it's not important.
