Paint your bedroom purple to boost sex drive

It found that couples with purple-themed bedrooms have sex on average more than three times a week, slightly ahead of those who prefer red, the Mirror reported.

For those inspired by EL James's Fifty Shades of Grey, they would hardly make love twice a week.

The survey of 2,000 adults by online retailer Littlewoods.com also found that lovers who sleep on silk are active between the sheets 4.25 times a week - more than anyone else.

Those who prefer cotton average 2.72 sex sessions, nylon 2.35 and polyester 2.33.

"For years I have been telling British homeowners, a beige bedroom makes for a beige sex life. That's one thing I wouldn't want to wish on anyone," the Mirror quoted Laurence Llewelyn-Bowen, Homes Style Expert for Littlewoods.com. as saying.

And the sexiest combination is purple walls, lilac silk sheets and a violet duvet cover.

The Littlewoods statistics revealed that couples adopting this heady mixture of colour and texture would have sex more than five times a week.
