“Sex” tells the story of what seems to be an innocent encounter at first, which then escalates into, well, sex. It appears on The 1975’s debut album. It was originally released on one of their first EPs and produced with help from Little Comets.

In an interview with Last.fm, frontman Matty Healy said:

The song is a love letter to every prudish 17-year old girl. Everyone’s been there with that indecisive, flirty girl who just can’t make her mind up.

He went on to talk about how the song is labeled as brash due to its rough drums and guitars, but he calls it “romantic.”

Two versions of this song’s music video exist: the EP version and the explicit/album version, released July 26th, 2013. The newer one breaks away from their usual black-and-white aesthetic.

The main idea behind the new video for “Sex” was centered around us wanting to incorporate a narrative that acted out the lyrical content of the song. It felt important for the narrative to be the true story of lyrics. So many of our tracks are based on real experiences, it was integral to have an honest portrayal of this. The make up of our music is centered around the juxtaposition of very honest, often self-deprecating personal stories set against uplifting major chord progressions. It is this dualism and notion of “sound tracking” our own lives which makes us cite John Hughes as such an important influence.
