phallometry

The study of the penile dimensions of male human beings. This can be conducted informally, e.g., a heterosexual woman vetting a potential lover on the basis of his purported or observed length and width, or formally, as when a clinician or condom manufacturer collects data through direct measurements, surveys or some combination of these.

Wanting to shed her reputation as a "size queen," "cockhound," and so on without sacrificing her preferences, KittyJane decided to start putting "expect phallometry" in her online personal ads.
