It all depends on the position of the woman when you notice her. Facing you I would say face most of the time first, but followed shortly would be breasts. Facing away from you we all look at the ass. In fact, that's what first attracted me to my wife. If it hadn't been for that I may never have noticed her because I was just getting out of a bad relationship and I wasn't looking for anything at that moment, just looking forward to having some fun, but that thing was smoking!!! So I had to act on it. And now 7 years later (tomorrow) and three kids later she's still got it.
