Funny to read this thread after not posting on this website for some time. Men with breasts letting testosterone remain in charge. I hope everyone knows that it is estrogen that contributes to development of gynecomastia. This website was started by a gay man with breasts he wasn't excited to have. He cut them off and then sold this site to the doctors offering that service. Men on this side of the forum are choosing to accept the breasts that have developed on their chest. It is a tough place for a macho man to stand. In a world where the younger generation is much more gender fluid, I guess it isn't surprising that the old men who arrive at this site, sometimes because of drugs taken for this or that reason creating breasts, would resist the notion that feminizing could be part of the whole process.
My former wife bought me a woman's purple turtleneck a few years ago not because I needed it to accommodate my breasts but because I couldn't find that color on the men's side of the aisle. I've been frustrated for years because I like color in my wardrobe and folks producing clothes for men seem to think color is for women or gay men. I'm neither but I love color. I looked at the link OP included at the beginning of this thread and was delighted to see the colors on offer. Alas, I also have fairly broad shoulders and that purple turtleneck simply didn't fit well. I don't think I'll get color in my wardrobe this way.
So men here wear brassieres, sometimes wear panties, like women's shirts that provide room for their breasts, talk for years with other men about having breasts and sometimes say they'd welcome larger ones, then talk about the best brassiere to buy... and are offended if someone goes too far in saying they want to feminize themselves. Testosterone wins again... more's the pity.
