Competition: to celebrate Valentine's Day, Dezeen has teamed up with UK studio Dorothy to give readers the chance to win one of five posters filled with suggestive vocabulary (+ slideshow).

Congratulations to the winners! Jennifer McHugh from the USA, Jessika Brunner-Gnass from Canada, Joseph Saxby from the UK, Andreas Nikolopoulos from Greece and Eugene Ong from Singapore all won a Periodic Table of Sexual Terminology poster.

Dorothy's Periodic Table of Sexual Terminology is designed in the same format as the Periodic Table of Elements, created by Russian chemist Dmitri Mendeleev in 1869 to visually categorise the chemical elements.

For this more provocative version, Dorothy replaced the chemical symbols with 114 abbreviations for words or phrases related to sexual acts and affiliated body parts.

"There's everything from the obvious f-word and the straightforward 'screw' and 'shag' to the slapstick 'how's your father' and a bit of 'hanky panky' to the more imaginative 'horizontal hula' and our studio favourite 'bumping uglies'," explained Dorothy.

"Some terms you might already know, and some you might never want to know," the designers continued. "There's even a useful guide to alternative words for his 'n' hers bits 'n' bobs just in case you're struggling to locate the 'panty hamster' or the 'swizzle stick'."

The graphics are printed in hot pink on a scarlet red background, which is sized 80 by 60 centimetres.

"The Periodic Table of Sexual Terminology is more of a rummage around in Dorothy's school boy (girl) mind than a scientific investigation into the finer linguistics of sex," said the studio. "It's not for the faint-hearted."

The posters are available to purchase from Dorothy's website.

This competition is now closed. Five winners will be selected at random and notified by email. Winners' names will be published in a future edition of our Dezeen Mail newsletter and at the top of this page. Dezeen competitions are international and entries are accepted from readers in any country.
