Drunken fumbles: we've all had them.
As a result, the intimate act of undressing in front of a stranger and getting into bed is often smeared with hazy memory, all inhibitions laid bare thanks to a hefty pair of beer/wine/tequila goggles.
So what would happen if you got 20 strangers into a room, and observed them undressing each other?
Filmmaker Tatia Pilieva's "Undress Me," a sequel to her popular First Kiss where a load of strangers locked lips, set out to explore that brief period before intimacy.
Pilieva was inspired by the work of William Masters and Virginia Johnson, who were pioneers in the research of human sexuality.
They also asked strangers to get in bed together.
What you see in the video is what happened unscripted, from every hug, kiss and look.
"I asked strangers to undress each other and get in bed. Nothing else. No rules," writes Pilieva in the video description.
It's surprisingly intense.
