My brother and his friends always tease and mock me!?

My brother is by far the most stuck up self centered person on earth. he thinks hes the best person ever and that he runs our house. but no he doesnt hes stupid and extremely naive. him and his friends always mock me by calling me gay but not directly its confusing. im not gay tho and idk y they think that. they always say embarring things to me when we're in school. theyll be like hi in a baby voice when im with my friends. and touch me its so annoying. they think they can just push me around but im dang tired of it. my brother and i always fight over the xbox and he thinks he owns. apparently he bought it with his own money but i know its not true. he always tells me to get off but when i tell him hes like no im playing. im thinking i should give him a taste of his own medicine when im playing the xbox. and he blames every problem of the xbox on me. like today he said i messed the up settings on his headset for the xbox and he went crazy and said i couldnt use them. but i no hes really stupid cuz he was like studdering it was funny. i hate them so much any advice u cna give me??? sorry if my question is indirect and u cant understand it im just so tired of this stuff he and his friends have been doing to me. i have so much to say idk how to say it.
