You can apply eco-friendly principles to pretty much every aspect of your life. But even ... your sex life? Yep, according to this article from TreeHugger. They've listed some things you can do and products you can use to protect yourself, protect the environment and still have a great time with that special someone. Some tips?

• Shower together. Not only do you save water, but you are sure to have a steamy time.
  
• When it comes to lubes and lotions, go for the ones that are as natural as possible -- so without artificial colour, scents or tastes. You can even find organic products at some stores.
  
• Try bamboo sheets on the bed -- they're sensual and slippery.
  
• Try some natural aphrodisiacs. Herbs like ginseng and ginko biloba are rumored to be aphrodisiacs, plus some food items like strawberries, oysters, chocolate and wine. Know of any others?
