I only started hormones a couple of months ago, so I don't have anything more than some serious man-boobs. I imagine that when I start seeing some areolar development it will be quite a fulfilling feeling.
However, getting my ears pierced was a big, big step for me, perhaps the bravest thing I have done so far. I was scared to death of negative comments, primarily at work. I got one neutral comment, "Did you get you ears pierced?", one incredulous comment from my wife (I'm separated), which eventually led to me admitting to her that I am transgender, and one in-your-face comment, "What's up with the earrings?", that from a man at work.
He went on to say, "Usually when a guy shows up with pierced ears, it's either a mid-life crisis, or because of a woman." I told him, yes, it was because of a woman. I didn't mention that the woman in question was me.
