Hi, crazy, but I did this yesterday. First off for him it wasn't much of à surprise.
But I asked him a rehtorical question about dysphoria, and then in a couple of paragraphs told my story. No embellishment, no apology. We now ha e a conference call with HR next week, and an all hands meeting scheduled for June 11 to make everything public. For me it went well. I hope it goes that way for you.
