Maybe I'm being pedantic in interpreting the semantic of what you wrote, but the fact that a certain feature is recognized as sexually attractive and produces a release of hormones does not imply that there is any special physical wiring between your neurons allowing it.

Actually, we are at the point of the research where we are still asking whether we can understand basic facts about the brain by its physical wiring (e.g. we have a complete map of C. Elegans neural network of 302 neurons but can't simulate it).

By the way there is no need for a special physical wiring in order to have innate preferences, but I don't know whether there are some or not. I heard somewhere that breasts evolved as they are now to resemble the shape of a butt, which our ancestors found attractive probably even before the time of the Homo Sapiens. We also know that in different part of the world there are different features that are considered attractive (I'm thinking about beauty standards in remote tribes), so it might also simply be a social construct.
