Congratulations.

One more step down, plenty to go! I had an experience earlier today. I wear rubber padded cut resistant gloves for the work I do so when I went to adjust my safety glasses I pulled a lot of hair by accident, cringed, and proceeded to remove the hard hat, hoody, glasses, and all that to fix it all.
The lady (coworker, lesbian, great gal) across from me said, "Geeze, all that hair. Why are you growing it out?" I responded with, "To keep my ass warm!" (it's pretty cold where we are). She replies, "But that's not your butt." And I said, "You sure?!" We laughed. Few minutes later I said, "But nah, if you thought really hard about it you'd figure it out."
We've had discussions relating to LGBT things given that we're both a part of it. If I was to ever have an ally in the workplace it would be her. That's the closest I've came to ever telling someone in the workplace, and probably the closest I'll get for a long time. So kudos!
