Well, why not? We're all adults here.
To be quite honest, it never occurred to me to wonder whether or not organic lube or phthalate-free sex toys might exist. In the heat of the moment, sustainability is on my mind... but not the ecological kind. If you know what I'm sayin'. Ahem. It makes sense, though, and it's good food for thought, if not practice; After all, if we're going to be conscientious and careful about the ingredients of the food that goes into our mouths, and the clothes that go on our bodies, shouldn't we also be mindful of what goes into the little helpers that go into our... uh... (insert orifice here)...?
If it's important to you to go as natural as possible while enjoying each other in the bedroom, TreeHugger is a great place to find out how, where and why to spring for organic bamboo sheets, petroleum-free lubes, natural aphrodisiacs, and more. Of course, showering together is a great way to conserve water, and snuggling under the covers is a surefire way to keep the heat turned up without having to turn up the thermostat... but if you're looking for a little more... well, look no further, my friends.
Oh, and while you're visiting TreeHugger, watch this video, won't you? Brings a whole new meaning to the term "healthy sex life."
