No, we don’t mean dirty in the sexy “talk dirty to me” kinda way… we mean does it make you feel unclean– like you need a shower? According to one study, thinking about casual sex leads people to buy hygienic products like soap, toothpaste, and face wash. Via Phys.org:

New research by Australia’s Monash University shows that highly sexualised imagery in advertising causes some consumers to feel “physically dirty” and motivates them to buy products such as toothpaste, soap and face wash.

This international three-part study involving more than 1600 participants from the USA has found that reminders of casual sex, perpetuated through advertisements for merchandise such as perfume and lingerie, might have an unintended effect of turning people to buy personal hygiene products.

Hmm, if you ask us… casual sex doesn’t make people FEEL dirty, it makes them want to “tidy up” so that they’ll feel squeaky clean in case of a surprise hook up! What do you think?
