I thought it was fascinating. It's not a scientific paper but an article for general consumption. The sexuality comes into play when measuring what type of erotic stimuli people found arousing. The were 2 measures of arousal; one subjective (what people self reported) and objective, sensors that measured physical aousal.
Males were as expected. Hetero males were aoused by hetro erotica and lesbian erotica, but not gay erotica. Gay males were aroused only by gay erotica. The physical and subjective measures were consistent. Females, regardless of sexual preference showed physical arousal to ALL the erotic stimuli. There self reported measures however reflected their sexual preference. There's more to it than that but thats a nutshell version of her findings.
