You guys totally crack me up!
DH (who works on corporate America - no infection control, or danger issues) has stopped wearing his ring for several years. I'm not excited about it, but have dealt with it. He, however, claims he was hit on much more when he wore it.

(Travels a lot for job.)
I wear a band w/ set in stones, to avoid snagging tender skin and/or gloves. But, w/ good handwashing and a responsible use of gloves I've never worried about carrying little bugs. I have also seen people wearing their ring(s) on a saftey pin attached to scrubs. But, that seemed to me like asking to accidentally lose it...
