I assumed Stardust was female.
Stardust has been referred to as a "he" repeatedly in its appearances, iirc. When it fought BRB, during Annihilation and the Heralds spinoff. I can only recall it being referred to as a she in one of the F4 series. Its an ethereal anyway, and they exist as pure cosmic energy. It's a pretty fair assumption to have it be sexless.
