guuuysss, wat do you like in ladies?

me and my cousin hang around my dads neighborhood and we hang out with alot of these boys.. im 16 and my cousin is 15 (almost 16) but the boys we hang out with are 13, 14, n 15.. theyre are these 2 boys (one's 14 and one's 15) and we think they're maddd sexy and we want to chyll with them sooo bad all the time.. we text and hang out with them sometimes, but other times they totally deny us ignore us.. we're willing to do whatever they want with these boys, (not that we're hoes and do that with anybody, but we reallyreallyreally like these boys) and im pretty sure they know that.. the 15 year old boy has a gf but hes always tellin me that he doesnt.. me and my cousin are good looking and were chyll and not annoying like the other girls they hang around with.. i dont know what else to do.. why dont they want to be with 2 older girls? what do you think they are looking for?
