I believe God made women of all different shapes and sizes so that us men can delight our senses in enjoying the wondrous beauty of God's creations. Now, by no means am I insinuating lusting after multiple women, but there is nothing wrong with taking the time out of your day to ogle a woman and let your eyes roam up and down her body and let your imagination take hold. Why, even though I'm a True Christian™ pastor, I still do this at least 50-60 times a day, practically with every woman I meet. Yet I am still faithful to my wife and don't lust after women.
So I would respond "Yes" to small-breasted women. As the old saying goes: "Good things come in small packages".
