The ubiquitous Eew! Factor—an excited disgust—is layered. Its tangled experiential and constitutive dimensions unfold when the Eew! Factor is examined through the lens of sexual countertransference; sexual countertransference through affect, abjection, and intersubjectivity; and sex itself through all of them. Taking the perspective that sex is neither psychic bedrock nor diagnostic sign, this essay examines three expired, not entirely successful, cases in which this sexual disturbance, which all clinicians, like as not have experienced at one time or another, appeared. Receiving particular attention are matters of transference-countertransference lust and erotic unknowing; racism in the clinical setting; and shame, embarrassment, and humiliation in relation to gender and sexuality.
