Well, my earlier post was on the task of telling friends and family. That alone is a big hurdle.
Co-workers is a whole other ballpark. Took me years to admit to my coworkers about being gay. Poly? Oy. That's scary and unpredictable. This is still the South here afterall---most folks here are religious in one way or another. So far, I think my coworkers have this sense of feeling like they are "enlightened moderate" Christians who are tolerate or even accepting of gays. But polyamory would certainly go over their thresholds, I'm afraid.
