I think the reason that W tries hard to hide it is that she doesn't believe it is right herself or she is embarrased of her own choices.
This is ofcourse speculation. I do see though how As don't last though. I think in my case (mmf too) that this is twice as true due to the fact that our Ws are carrying on homosexual As. As much as the popular media would have you believe that it is a perfectly acceptable thing to do, I thing the public at large really frowns on it and this is just another thing that W has going against her. I can't imagine W carrying on this R in front of her mother, sister, cousins etc.
