Well that seems like a strange question...
I always wear my wedding band. I take it off when I shower and when I'm doing something especially dirty (working on my car, painting the house), but otherwise it's on my ring finger.
My wife takes hers off a little more often, but I suspect it has to do with the fact that an engagement ring (not a wedding band) has a bit more bulk to it due to the diamond. But she still wears it more or less whenever she's out of the house.
What's the argument against wearing a wedding ring? It just seems like a normal, acceptable tradition to me.
