Experimental design. (A) Schematic representation of the experimental design consisting of a fixed order of presentation in which the sexual video clips were randomized across subjects. Each order consisted of three identical conditions, each composed of a sexual video clip (blue), a neutral video clip (red), a rest period (light gray), and self-report measures (yellow). (B) Example of Genital responses (PT) collected during the sexual video clip with baseline, onset of erection (OE) and sustained erection (SE).
