Watching pornography before going out on a first date makes it more likely to go well, according to a new study, suggesting that so-called 'sexual priming' before dates can actually make men and women more open and outgoing. The study of 246 heterosexual undergraduates also found that merely thinking about sex makes people more likely to disclose personal information. It found this to be true for online interactions such (as via Whatsapp) and face-to-face meetings. Students who were shown a naked picture of a member of the opposite sex for just 0.03 seconds were more willing to go on a blind date than those shown a picture of a fish. The study concluded that 'activation of the sexual system encourages the use of strategies that allow people to become closer to potential partners.'
