Pretty much only on a need to know basis... until just a few months ago. During a break at work, some of us were talking and one fellow made a somewhat disparaging remark about the transgender people. I told them that I've dated TG women. When that fellow's follow-up question was if she'd had the SRS/GRS surgery, I reply no. "OMG! You've actually touched another cock?!?!" I told them of course I did, I'm Bi, I've no problems with that. I suspect that outing myself to my work group has opened a few eyes.
