Guys tease me about big butt?

There is nothing that will make boys stop being boys. they are immature and im sorry that you have to suffer for it. Having a big butt is a wonderful thing in this day and age, too many girls are so skinny and look like they haven't eaten for weeks. Embrace your curves because I guarantee you that all your friends are jealous of you and want your butt. As for clothes, Macy's has a line called Airya that is made for girls with butts :) good luck and keep your head up.
