In my opinion, you should definitely consult with a physician and be as honest as possible with him/her. To me, this is clearly gynecomastia, but you need to figure out what that diagnosis means to you? This forum tends to lean towards men that have accepted and are on-board with their chests; that position may not be right for everyone.
If this were me, I'd be asking myself how I feel about wearing a bra. Does this make me uncomfortable? Is the feeling the same while around both female and male company? I won't beat around the proverbial bush here; I think bras are "for the support of breasts", and while they were clearly designed for women, there are so many men out there that, quite frankly, have breasts that need support.
I've personally grown more and more towards accepting "what I have" over the years. In my case it's not true Gynecomastia, but I do have (fatty) moobs that would threaten a great deal many women. It's 2022. A man should be able to do whatever they want to make themselves feel like themselves. Things like earrings, tattoos, fancy clothing, long hair, and yes, Gyne ... all of these originally male things were identified thousands of years ago and embraced by men.
