My darling, delightful, SNARKY coworkers

I work with the loveliest, snarkiest group of people ever. Of the forty or fifty of us working, I'd say a good 75% are gay men. I remember my first day on the job, my manager looks me up and down and first thing he said was, "Oh girl, you need a pedicure." Right....thanks. So that sort of set the tone, and since then, we're all incredibly inappropriate and almost always off color. I could not be happier. There's pretty much nothing that hasn't been said, and nothing I'm ever actually offended by. We have the best break room conversations ever.
That said, I was mildly offended a few days ago. My manager and one of the receptionists looked at me and said, "Anna, you're looking really good. Whatever you've been doing is working". I was all happy and preening and of course that got followed up with, "yeah cuz for a while there you were getting really fat...." :grumble: Of course someone else jumped in with, "yeah, I didn't think you were getting fat so much as I was thinking black guys would love you"....sigh.
The part that offended me was that no one bothered to comment on my weight gain to me. I would have liked a heads up, because I was pretty much lying to myself and still thinking I was hot ****, even though I was wearing stretchy pants almost exclusively. I asked them to tell me next time I started getting fat again, and they all looked horrified by the idea, saying how mean it was.
I'd much rather have someone tell me I'm getting a little too wide face to face then to have it be discussed behind my back. Am I alone on this?
