Brother not into me

So idk why but I cannot get my older bro to look at me like’that’ and I’ve been trying for months now. I do all the usual hot outfits around house or extra touchy with hugs and he barely looks at me I just want to be taken by him can someone tell me what I’m doing wrong all my friends say he’s hot and they want him and I just want him to look at me like he does them even asks when they are coming over but not ever to hang w me
