Vaginal photoplethysmography is a method for physiological evaluation of sexual arousal in women. This paper undertook to obtain the validity and reliability of a set of sexual stimuli in young heterosexual women. Six six-minute video clips were selected. A total of 34 women aged 18-30 years(M = 22.38, SD = 2.52) participated in this study. Objective Sexual Arousal, Subjective Sexual Arousal, emotional activation, emotional valence and socio-psycho-sexual information were evaluated. Three of the six sexual stimuli were selected from the scores obtained after the experimental phase. It was observed that the aforementioned video clips produced the most arousal-activation-pleasure, with internally consistent measures. As expected, good indicators of external validity were observed, with statistically significant differences. According to the data obtained, the pooled use of the three stimuli increases the like lihoodof obtainingan objective arousal response in healthy young women, there by minimizing the possibilities of displeasure.
