Forget hot wax and nipple clamps. The darkest and most twisted examples of sadomasochism are found under beds and in sock drawers the world over. Consider the phthalates-rich butt plug, whose toxins are slowly poisoning its user’s body via the holiest of holies. Or the discarded rubber dildo, buried in a landfill and contaminating the groundwater. These instruments of pleasure may in fact be causing environmental and biological pain, Molly Freedenberg writes for the San Francisco Bay Guardian. And while their actual impact may be overstated—especially in comparison to other harmful, more widely used items—its not difficult to play it safe and find these same items made from more eco-friendly (but no less user-friendly) materials, like the seaweed-based dildo created by Love Piece. Or get creative and make your own. Just don’t forget the sandpaper.
