That’s according to this article. It doesn’t explain quite why those with a purple bedroom have more sex. Apparently people with silk bedding also have more sex than average. Those with purple rooms have 3.49 sexual encounters every week whilst those with red rooms have 3.18 sex sessions a week. People with grey rooms have the least sex with only 1.80 times per week. The figures come from retailer Littlewoods.com. How reliable they are and who was surveyed is not clear from the article.
