 Sexual objectification is treating or considering a person only as a sex object. Casual sex, watching pornography, catcalling, ogling, and other examples all allegedly involve sexual objectification. The “only” is important because otherwise there is no basis for moral complaint given that we frequently treat each other as objects. It is unclear whether objectification can consist of mere mental regard or whether it must have a treatment component (ogling someone is interesting because it is unclear whether it is treatment or mere regard). Some philosophers (Papadaki 2017; Langton 2009; Nussbaum 1995) define “sexual objectification” broadly enough to include mere regard (others, e.g., LeMoncheck [1985: ch. 1] do not). The inclusion of regard is wise because objectification seems to involve mere attitudes and perceptions (e.g., ogling, the regard found in watching pornography). X then sexually objectifies Y if, and only if, X treats or regards Y only as a sexual object.
