This is a question for the professionals. SPs, way back in the day I had a waterbed in college when they are all the rage, very bad though for a bedroom floor in a house due to the weight of the mattress. Question is have you ever had sex on a waterbed? Was it pleasurable as they say to have sex with the motion in the ocean or did you not care for it? I remember some mattresses were firm and others had more movement and had a lot of give. I liked it then my college girlfriend like it as well, although today at an older age I think it would be harder on my back. When you are young and dumb all you know is that you are fucking as Eddie Murphy once said. The heat feature was nice in the winter though.
