That would have sent my mood downhill real quick. I would have loved being accepted like that, but the lack of period (I've always wanted to have to deal with that, believe it or not) and fertility/ability to carry and give birth are on my very short list of strong dysphoric triggers. I can put off the feelings most of the time, but if that was said to me, it would've been a kick in the gut to me.
Bask in it while/if you can though, and if your pic is anything to go by, I'd have never known you were anything but cis.
