The underwear company that carried out the poll was researching the sexual preferences of several countries including China, France, Germany, Holland, Italy, Spain, Sweden, the UK and the USA..
Apparently, the international average interested in illuminating underwear stands at 23%. Germany is the country least fond of the invention.
Meanwhile, most people in Spain and Germany prefer to keep the lights on in the bedroom, while Brits, Americans and Swedes are among those most likely to turn their lights off.
Up to 20% of Americans, Swedes and Germans cite their lack of self-confidence as the reason for having sex in the dark, while 20% of Chinese men do it in order to think of someone else.
44% of Germans were found to be the most drawn to tools and gadgets in bed, with people in Spain and China closely following.
This doesn't seem to be an issue in Spain and Italy though, with people in both countries liking to have a mirror in the bedroom to improve the experience.
Swedish tennis star Björn Borg's company was behind the survey, asking 1,713 respondents aged between 18 and 30.
The 'Lights Off Survey' coincides with 'Earth Hour' on March 31, which encourages the world to turn off non-essential lights for an hour.
