While I do understand your point, these days ANY parts of the body are being modified to suit, so having a good backside isn't always down to working hard to keep in shape!I would say that given that the breast is generally something you are born with and is genetically predetermined in size (unless you purchase the size/shape you desire) and the butt is something you have to work on to keep up it's shape, I would go with backside.
If a woman is breastfeeding out in public then it's obviously out of order to stare as that would be just plain wrong, so I can see what you mean on that score.I prefer the backside because I've never seen breasts as something that you drool over. My opinion is that they're made to feed kids and are there just for that, not to be stared at. Boobs are beautiful, no lie, but I like healthily round backsides more.
I go with the ass as well, not having a nice ass is a disappointment for me. I will end the relationship, hell I won't even start it to be honest if the woman I'm interested in doesn't have a nice thick ass I can grab on.I would say that given that the breast is generally something you are born with and is genetically predetermined in size (unless you purchase the size/shape you desire) and the butt is something you have to work on to keep up it's shape, I would go with backside.
