DIY LUBE
Materials: 1 cup water, 4 tsp cornstarch
Mix water and cornstarch in a small pot, cover and heat on a stove at medium to low heat. Stir often to keep cornstarch from sticking to the bottom of the pot. Shortly after it comes to a boil (three to five minutes), it should have a smooth consistency. Pour into a bowl to cool and use within a few hours or a day—do not refrigerate. The final product may have a Jell-O–like skin, but the insides should be gloppy goodness if you use it immediately. Keep your homemade lube out of the vagina or anus, however, to reduce the risk of irritation. Best for masturbation, hand jobs, or, if flavored (mix in half a teaspoon of vanilla extract or orange zest), oral sex. —Debby Herbenick
