Red is the colour of passion and hot-blooded romance. Invest in some sexy scarlet lingerie or nightwear to give both you and your partner a sensory boost. Perhaps unsurprisingly, lots of red foods are natural aphrodisiacs. A glass of red wine will help put you in the mood, and strawberries have long been said to have passion-boosting properties (especially when hand-fed to your lover!) Or why not really spice things up with some chilli-laden food? It may sound counter-productive, but red chilli peppers stimulate endorphins (the brain’s feel-good chemicals), speed up heart rate and make you sweat, which all mimic how you feel when you’re aroused. Just don’t put too many chillies in your dinner or you’ll be reaching for a glass of soothing milk instead of each other!
