My wife helped me with stuff like this. She told me that, while men will open the door, wait for the woman to go through, then go through themselves, women will open the door, go through it, and then hold the door behind them for the other woman. Similarly, when unlocking our car, I used to open the passenger door first for my wife and then go around and open mine (we don't have one of those electronic clicky-box thingies). She told me to open my door, get in, then reach across to unlock hers.
I am getting used to it. Yesterday, we were building sets at a theatre. I was sawing and using an electric screwdriver and stuff. But when it came to lifting 8'x4' risers, I just stood back and let some big strong men do it for me. In the old days, I'd have been right there lifting. Hee-hee!
