So many types of people, it will obviously be impossible to please everyone. The relatively low numbers on this site looking for support garments also makes it impossible to dice up the topic sections too much. I think people will have to accept not only their breasts but also that the flavor of this site will not always be theirs in each and every post. It is simply unrealistic unless you want to start your own forum of one.
I have had breasts since I was 13 to live with. I did not have internet or any other help to navigate my way. I tried a bra in response to curiosity from all the comments I had at school that I needed one. While the initial discovery of how well my breasts fit a bra gave some excitement to a young teen ager, it settled down with a growing realization that a well fitting bra gave comfort and no bra was irritating much of the time.
I have always gravitated to a more plain T shirt type bra that seemed to fit well without calling too much attention. I have always felt sports bras were overly massive contraptions that did not fit the purpose of daily wearing, (in fact they were made for a specific use and not to wear all day every day). While pullover bras were cheap and not usually comfortable.
Some here begin to explore more extravagant bras than I will ever likely get. Does not bother me. By definition in todays society a bra is a feminine item anyway, no matter the style. I am happy with plain but functional bras for my needs, but others want to enjoy the concept further, sort of if your in go all in. Some like plain pick up trucks and some like to bling them to the max. There are those who simply and quietly put up with having breasts and discovered comfort with a bra, and those who begin to enjoy having breasts and treat them more like a women would perhaps. And those that enjoy having breasts may be more inclined to enjoy feminine clothing beyond a bra.
Basically, a man having breasts is a spectrum from; hate/surgery, to tolerance/exploring comfort options such as a bra, to exploring enjoyment options of having breasts and its uniqueness with more involved garment options. Many may move along the spectrum over time and change their attitudes.
So with our relative small numbers you have to accept that you can not always have it your way and to tolerate others as you want people to tolerate you. You may even change your position over time too.
