I guess... just weird that my brother sleeps and plays video games all day has pretty wide shoulders.
That's because he developed them during puberty. There's a difference between naturally wide shoulder bone structure and built-up muscular shoulders. As you're not still in puberty, just assume they won't grow any more naturally. So exercise is your best option. Also realize if you mainly isolate your shoulders in workouts rather than your entire arms, and don't lose a lot of body fat, you won't look like the MMA fighter. You will build muscle under fat, and won't have the definition on the outside, you'll just be a bulkier squishy.
T is the hormone in puberty that grows your body into a male structure, while E grows it into the more petite female structure. That's why your shoulders are small while your brother's are larger. Because of my PCOS and overall messed-up hormones, I grew wider shoulders and very narrow hips, while every female in my family seems to have grown the opposite direction. However, because I'm still genetically female and my body did produce SOME E, my shoulders still are not very wide for a male, rather, they're on the more petite side for a man. But in the week and a half I've been working out again, I HAVE noticed some more muscle around my shoulders already. They don't look incredibly muscular because I've still got a lot of fat to get rid of. But they're definitely wider, more defined, and more masculine.
YES, some people have claimed to have continued to grow their natural bone structure through their T-induced second puberty. But don't ever assume that it will happen to you, as chances are good that your growth plates have fused and you're done growing. Assume that it won't happen so that if it does, it's a welcome surprise, but if not, you won't be disappointed.
Just some food for thought.
