Kleinplatz and physician Charles Allen Moser argue that paraphilias should be removed from the Diagnostic and Statistical Manual of Mental Disorders (DSM).^[9] Kleinplatz wrote, "[T]he DSM criteria for diagnosis of unusual sexual interests as pathological rests on a series of unproven and more importantly, untested assumptions."^[10] Therapists who focus on "functional" versus "dysfunctional" sex, have an approach, she writes that "is, at best, limiting and constraining and, at worst, dehumanising and risks exacerbating rather than alleviating suffering."^[11] Kleinplatz criticized sex therapy as being "too performance oriented," and not focusing enough on desire.^[12] Her work has been to focus more on ways that partners can please one another by learning to listen to what their partners want.^[13][14] Kleinplatz has shown that "great sex flourishes in relationships that deepen with maturity," according to the Globe and Mail.^[15] She has also criticized the concepts premenstrual dysphoric disorder^[16] and dyspareunia as medicalizing women's bodies.^[17]
