How is my younger brother stronger then me?

Anonymous
So im 16 and 5ft 11, My brother is 15 and 5ft 8ft, He is lean but im taller and im more bulky then him, But we had a wrestling match at school, I was quite literally powerless, i was being thrown around easily, I literally could not get him off me if my life depended on it, This little f*Cker can bench 225 pounds LIKE HOW! , He is short lean and on the skinny side, Im taller then him i have more muscle and i can't bench NOWHERE near that i have to have to ask him to lift things for me sometimes , are guys really THAT much stronger then girls on average? My boyfriend is also the same height as me and skinner then me and has less muscle, But he is still strong as f*Ck and much more then me? but side by side i would look like i would be the stronger one, How?
