 Sexual orientation is commonly understood as a person’s standing sexual preference for men, women, or both. It is a basic preference, unlike, say, the preference for blondness or buttock size. It is also an organizing preference: other sexual preferences are built upon it (Stein 1999: ch. 2). A foot fetishist is either gay, straight or bisexual, before he is a foot fetishist, though it is an empirical question whether there can be sexual orientations for body parts (or objects) regardless of the gender or sex of the person’s body part (Stein 1999: ch. 2; Wilkerson 2013).
