Something similar happened to me about 1 or 2 months after i went full time, by that time i was about 7 or 8 months HRT and went full time 6 months because i thought i looked more female then male, so decided it was time. I met my X-wife (we are good friends) and we both went to the movies together. We were standing in the lobby talking about this and that when this guy walks up to my X-wife and starts to flirt with her. I think this is great because she could use this as maybe a way to nudge her to move on from our past relationship (we broke up a year before, but not due to the TS thing, a separate issue). Well after about a minute talking the guy turns and looks at me and asks, "So why dont you introduce me to your beautiful friend here?", then proceeds to make moves on me. Apparently guys use friends to open doors to ask another girl out, I didnt know that, and really, i think its rude, but at the time it was a shock that this guy was actually hitting on me. To which my X-wife's only response:
"YOU DID NOT JUST HIT ON MY X-HUSBAND!?!!?" The guy took a back, and i sarcastically smiled without saying a word. He backed off and we went to see our movie. I wasnt ready to date, so it kind of fixed itself, although she was distraught about it later, i mean who wouldnt be right? but the guy just might have been into tall blond women, and she was Asian, so it may just have been a preference thing, because at the time, i thought she was way more better looking then I was.
