I'd like to weigh in over the matter of preference for larger breast - I don't think it has anything to do with being breast or bottle fed.  If we're honest, we'll admit that the breasts, especially the nipples, are sensitive erotic areas from which both sexes derive great pleasure - so we fantasize about their being bigger - much the same way men will obsess over the size of their organ.  But, it's a fantasy that works in a game.  In real life a balanced figure holds more appeal (as does perkiness over floppiness, anyday!).
