Do men prefer big breasts or small breasts?

it all depends on the guy. He could like big boobs, then while some like small. Most guys like big boobs though. well it depends on the guy and age. if the guy is into that kidna thing then yes he loves big boobs. if ur about 18 and the guy is looking for sex then of course he will like big boobs. some guys dont like it though....i dont know how to tell though
