"The media, and pornography, in particular, have a long history of depicting women as 'bisexual' while engaging in same sex behaviours for the pleasure of male onlookers. Recently, this experience, which has been labelled 'performative bisexuality', has become common place in bars and at parties where two girls/women engage in same-sex behaviour for the purposes of arousing men/boys," said Nicole Johnson, professor at lehigh University in Pennsylvania, the US.
