Use a shaker: first put in the ice, then add the orange juice ( you should always add the fruit juices before the alcohol! ). Put both the Passoa and the Malibu in and give it a good shake. Poor in a glass and add a cube of ice. The poor a bit of cream on top of the ice cubes ( preferably using a teaspoon or so to keep the cream from mixing with the other stuff ). Put a cherry on top and voila, there's your Sex on the Beach.
