I have gotten to the point where people look at my boobs constantly. For a while now, my reaction has been to take action to cover or minimize. So, the shirts got looser. When I was carrying something, I was hugging it to my chest. Walking around with my arms folded. Taking an aisle in the store with no one in it. Turning away to feign interest in something when people got close. Etc. etc. etc. (Curiously, GGs .do some of these things frequently – particularly arm folding and hugging things to their chest while carrying.)
It gets very old.
So if I am going to be out there for all to see, I have a choice between cringing and hiding all the time or just being myself. I choose the latter. So it's head up, shoulders back. Own it. A side benefit is that it's better for posture, but I digress.
This may sound terribly obvious, but clothing matters. Though anyone with a brain knows why women's tops are cut differently, you start to gain an appreciation for the details. Take the example of a men's polo shirt. With breasts, there is a pull that starts at the bottom of the button placket. It extends a line in the fabric to the point of each breast. In turn, that holds the front of the shirt up a little bit and makes it hang a bit tent-like like in the middle front. In fact, the entire lower half of the shirt, all around, winds up hanging wrong and looking a bit like a maternity top! Tuck the thing in and it only gets worse. Add to that the fact that whether you have buttons buttoned or not makes no difference whatsoever. They each look bad in their own special way.
So I think I'm going to shop for women's polos.
You read all the time that there are consequences to hormones. It is often not very specific, and people tend to minimize things as a result
Well, this thread gives you an idea of just a few details (there are many, many more).
People will stare at you. You will feel self-conscious (at least for a while). Your clothes won't fit properly and will look like crap on you. You will start to acquire that "in between" look that people write about here. Neither fully male nor fully female. You will confuse people and they will be hesitant with you.
Breasts. If you want them, you better be prepared to own them.
