Wearing a bra does let us take control of our appearance and presentation.
That was the biggest surprise for me when I started wearing a bra. I had the fear and paranoia that a bra would make my chest look feminine and it would be obvious that I had boobs so I MUST be some kind of freak or half breed of man/woman because bras are so identified as strictly female since they are marketed exclusively to women and are made with "soft and feminine materials" like lace and satin and emphasis the breasts.
The truth is due to the number of styles and types of bras, I found out very quickly that with support, I could shape and mold how my chest looked depending on the bra. A technique women do all the time. If a woman wants to draw attention to the chest, they will wear a bra that will emphasis the firmness/projection/size of the breast or if they just want to be casual, they will wear a bra that will support but doesn't have much projection or show off size. The top they wear also will determine whether their breasts show or not. Since women have smaller waists than breasts or hips, their clothing is tailored to nip at the waist, which will emphasis the breasts, men's clothes do not do that so does not emphasis the chest. I also found that with my breasts properly supported, there was no more movement to draw attention to them. So while my chest may have a feminine appearance when wearing a bra, with the proper bra and top and now no movement of the girls, eyes were not drawn to my chest. The bra also improved my appearance in the chest since my breasts were now supported and not just flopping around. Imagine a woman who is braless and one wearing a bra. You can tell a difference in appearance. The woman wearing a bra has a perceived better appearance and goes unnoticed while a braless woman gets the attention. The same is true for us as well. Its not all negative wearing a bra.
There are advantages to wearing a bra if you have breast tissue, man or woman. Remember, a male with true gynecomastia has breasts that are the same as a woman's, including the ability to lactate under the right conditions even though it is less common for men because we lack the amount of hormones needed to lactate, even though we still have the same hormones as women do, just smaller amounts. So our breasts will react the same way women's do, because they are the same! The difference is how much fat is deposited in the breasts and that is controlled by hormones or lack there of. So if they are the same, why can't they be treated the same? It's society that has the problem with breasts in general on a man much less a bra. If you have gynecomastia, your breasts are already on the radar. People are noticing whether they say anything or not. A bra becomes invisible at that point and can be a real friend, not a vile foe. Remember, we are all made of the same material. How it is distributed or stimulated in the womb by the sperm will dictate male or female. Male testes are female ovaries that develop outside the body and instead of creating eggs, create sperm. Same material. Genetics, driven by hormones dictates which it is. Many don't realize that so men with breasts is not as unusual as one might think. It's the reaction that is.
