 (1) There is no good reason to believe that there are only three sexual orientations. Many men are attracted to people with female features from the waist up but male features from the waist down (a penis). What is their orientation? Many men are also attracted to both young boys and women—this is true of many cultures around the world, past and present. Are they all bisexuals? It is also possible that some men are attracted to young people, both girls and boys. Is there a sexual orientation, then, for young people? And zoophilia threatens to expand the number of sexual orientations with no limit: genuine zoophiles—people who have long-standing desires to have sex with nonhuman animals—will have as many sexual orientations as there are different types of animals to which they are attracted (Wilkerson 2013).
