"Casual Sex" is a song by Canadian rock band My Darkest Days.

It was released on January 13, 2012, as the lead single from the band's second studio album, Sick and Twisted Affair.

The band revealed in an interview that the excessive nudity and promiscuity of the shoot caused tension between them and their respective significant others.

Matt Walst's girlfriend left him, while both Brendan McMillan and Doug Oliver dealt with turbulence in their romantic relationships.
