Sexual stimulants provide extra sensation. They include active ingredients like cinnamon oil, menthol, peppermint oil, and capsicum, that have an actual effect on the body - like tingling or increased blood flow to the area they’re applied. Stimulants can be used on the nipples, clitoris, G-spot, tip of the penis, and elsewhere. People use them for fun, to try something new, to get in the mood, or address decreased genital sensitivity as a result of medications, health issues, depression, or aging.
