I have wide shoulders too and im not thinking on any treatment as i like my male life as well, and go to the gym very often but when i dress and go out i try to intensify the hips and the buttocks so the body shape can have a proportion, even if m shoulder almost reach a meter in diam when you pass the measuring tape around, then i have to make my front look wider at maybe 1inch to each side than the shoulders width.
but yes when i am out and people can see something different in me is because I probably reach the 6',5" with heels and im living for the time being in China, where most people are not even 5' in heels, the shoulders are still on proportion at least.
So being over 6' tall and having wide shoulders is a relief everything is about proportion.
