Not to be that guy but I will in this case. If I have gotten to the point where I am thinking about marriage, firstly the girl more then likely what attracted me to her was beauty. From a guy's perspective no matter what anyone says out in public first seeing someone you are not thinking, "Oh this person has great personality." The first thing going through your head is how attractive that person is to your eye. After that then you begin to see everything else. The next flaw in this argument is not going into detail of the relationship before this question. I mean more then likely you have spent sometime with this girl and more then likely you went to bed with her on more then a few occasions, so obviously it didn't bother you then so why now? That being said, I think the question should be would I go after a girl who has a small chest, the answer quite simply is yes. I'm an ass man, I much rather have a butt that is round doesn't matter if it is big or small but ROUND.
