Lube is pretty great: it keeps you wet and helps you go deeper and longer without feeling any pain or dryness down there. Yet some things really shouldn't be used as Lube. Many people have been trying out different types of lube and opting for natural or "kinky" types of substances over water-based or silicone-based lubes on the market, but gynocologists agree: they don't have a place in your vagina. Avoid putting these "lubes" near your or your partner's vagina or penis . . . or things can get messy (literally).
