No, that's called preference, since none of them have a previous commitment to you, you have no commitment to them, therefore you can lust over whoever you wish, as long as you stick with that, there's a fine line between slutty and indecisive.
Alright let's go with indecisive cause I wouldn't be banging them all at ones, 2 guys from the school I went too and 2 guys from my friends school, all of them in my grade Expect one of them who is younger, I don't want them too see this though so I can't put their names down cause it would make friendships weird sorry
