A bit late to this party, but this sounds a lot like my position. Male all the way, both physically and emotionally, but happen to have a bunch of adipose chest/breast tissue that ebbs and flows in size for unknown reasons (I blame sodium intake or eating at Mcdonald's at any point in the past year - LOL). We may not have intentionally invited this into our lives, but we do need to deal with it as best we are able to. I think I've said this before, but a person that is both comfortable and confident with themselves will likely go unnoticed by others, if that is the goal.
Whatever your personal reason is to be here, be it looking for acceptance, support (physical or emotional), flaunting it, hiding it, literally "whatever"; I think this group of men are here for you and implicitly "good with" whatever you are feeling and legit want to help you.
If it helps, where I am today is that I am still "male all the way", but around two months ago my (adipose) chest tissue ended up becoming heavy and uncomfortable again without any reason after more than a year, that I could point to. Just being in a car on a bumpy road had become legit painful
I started wearing my Sports Bras again for a while to deal with this, and my wife claimed to be fine with this. Fast forward a bit, and the condition has subsided to the point where the bras are tucked away in a drawer again.
Next week my family and I will be in Orlando (Disney), and I do intend to pack a couple/few Sports Bras just in case I "boomf out" again. but I feel like I'm currently "ebb" as opposed to "flow" in this regard, which is a good thing for me.
Shorter version: whatever your reason for being here, you will ultimately find a friend that shares your particular walk of life. I have never seen a user here to make light of anyone's personal situation or be unwilling to provide a better link to follow based on your experiences/feelings.
