Dear Hubby and I are in a committed long-term, monogamous relationship and we don’t wear wedding rings. He never has worn his, he works in electronics. Shortly after the wedding he took a zap and flat out refused ever again. This is a man who is paranoid about static electricity. He’s taken one too many volts. I cannot tell you how much I enjoy wool socks in winter and sneaking up beside him and touching his ear.
So I suppose one might think it is a freaky genetic preference, but the fact is I did endure wearing it for years. Yet at some point the fact that I didn't like wearing it overrode the expectation to wear it.
