I'm not in transition yet and very much not out at work. However the other day, I was chatting with my coworkers and I made a comment about something with one of my friends. My coworkers commented that I only ever mention female friends, so I admitted that pretty much all of my friends are female, I've never really had strong friendships with guys (not counting the significant others of my female friends.) Anyway, my coworker then said jokingly "Oh, I guess that's why your so feminine." I wasn't really sure how to take it, but wasn't offended as her tone didn't come off as if it was supposed to be a real deep mocking, more just a casual joke. I think she thought she might have sounded offensive, because she immediately followed with "just kidding, you're very masculine." I wanted to tell her that I preferred the original comment.
