Sexologists appear to have lost sight of what science is about. They do not appreciate that before you can research a topic, you must first apply some common sense. There is nothing unscientific about basic facts and logic. Yet no one seems to see their relevance when it comes to understanding sexuality. In any science, the basic terms all need to be defined and understood. Preconceptions and assumptions need to be challenged. Yet sexologists have the same beliefs as the rest of the population.
