Accouple questions.
If you are wearing them to achieve a particular appearance externally, even a masculine one, and it works does anything else matter? Especially if many guys with normal gynocomastia wear bras both for either comfort and/or concealment? (You can always claim gynocomastia and blame meds. Lord knows that is the literal truth!)
If I get called on it I'll likely just be like "pfft. gyno, meds, whatever..." and ask the person how long they've been staring at my chest and why...
So in that sense is it actually even a gendered garment at all, or just something that people with breasts wear for various reasons?
If you identify as something other than purely male does it matter at all?
And even if you identify as purely male, it is certainly true that you have legitimate, use, for such an item.
Have you considered that both can be true at the same time? And that one doesn't invalidate the other?
Your question doesn't seem to be if it gives you the look you want, or if you can, but rather internal conflict over weather it is a CD thing, or an Andro thing. Maybe its just a boob thing, you have breasts and you want to look a certain way in certain circumstances, and it is a means to an end.
Internally, sometimes you may feel like a guy presenting the masculine image he wants to, other times maybe you feel more genuine to an androgynous identity. It doesn't have to be either or, or even both at once. It can just be a fluctuation, or gender fluidity. If the CD elements of your personality are happy perhaps that is a side issue, perhaps even a non-issue if your reasons are valid?
I find myself swinging a bit like a pendulum back and forth across the middle of the spectrum, never really being either binary, sometimes on one side, sometimes the other, sometimes middle. But currently to keep my day job undramatic I wear loose shirts, in six months I may wear a sports bra. Either way it is me being me, making my own choices. I am really not binary, so thinking in exclusive-or (either/or) terms rather than inclusive-or (and/or) terms made me mental and miserable.
Now I am rambling, but hopefully of some help?
