Since it might become relevant at some point in the future...
So your boobs will definitely get even bigger in the next months/years, but what if you come to a point where simply carrying them around becomes an issue? Would you be like "So what if I need a wheelbarrow to walk around, as long as I can have them bigger, I will" or rather "Okay, physically I could have another couple thousand cc's added, but I'm going to stop here because it will be too much to handle, even for me"?
