Arousal Gel: While not technically a lubricant, arousal gels are a (usually water-based) substance that can be applied to the genital region to increase a person’s sensitivity. Arousal gels are somewhat similar in sensation to warming lubricant (utilizing ingredients such as cinnamon and/or menthol) but are noticeably more concentrated/potent than warming lubes. Generally speaking, arousal gels are marketed for use on the clitoris, however, with more generous application, arousal gel can be equally effective on the head of a penis or on nipples. Some arousal gels come with variations including “cooling effect” or certain flavors.
