Juhana quoted The Atrocity Exhibition by J. G. Ballard
Patients were provided with assembly kit photographs of sexual partners during intercourse. In each case [Ronald] Reagan's face was superimposed upon the original partner. Vaginal intercourse with 'Reagan' proved uniformly disappointing, producing orgasm in 2 percent of subjects. Axillary, buccal, navel, aural and orbital modes produced proximal erections. The preferred mode of entry overwhelmingly proved to be the rectal.
