Butt all the way. I've never really found boobs to be that sexually pleasing, which is probably why most of my previous partners have had somewhat flat chests
People only say they like buts because that's what the media says what to like in a few years media gonna go back to breast and everybody gonna say they like breasts.What ever is popular like rap videos and movies and models that's what people gonna like.Back then in the early 90's nobody even knew what a butt was.
