Boobs are boobs. Guys like boobs. If a guy legitimately cares about your boob size, he isn't worth your time. Whether small or big, it doesn't really matter. Why? Because boobs! No need to be insecure about your natural body. Small and natural is better than big and fake.
What Girls Said
But what about boobs that are medium like a C and are both kind of big and real? It's the best of both.
Even better!
