Linger is "internal feminine flavoring" designed to help your partner "taste a new you." The website for the peppermint product notes that Linger is here to help the 72 percent of women who admit that they are somewhat self-conscious of their scent or flavor during oral sex.
According to the makers, the naturally sweetened mint is safe and shaped for comfort during insertion. But as our own visiting sex expert Dr. Charlie Glickman explains to Mother Jones, the mint contains sugar, which is not safe for the vagina. Thus, the manufacturers cover their tails by saying that the potentially dangerous mint is for "novelty use only." So I guess it's just supposed to be funny — are you laughing?
