I am a paranoid person in general. After growing my hair out, my wife and daughter gave me a gift certificate to get my ears pierced last December. All I could think about was "Long hair AND pierced ears? I will be outing myself!". I almost backed out and then went for it. I did get the ones that are a small hoop with the ball locked in it.
I work at a very conservative company and didn't get one comment. All I got was a few cools from friends. So unless it is expressly forbidden at work (I suspect there are companies like that out there), I wouldn't worry about it. Even my very religious mother just smirked a little and then let it alone.
