GoodHead Flavored Gel
I read the following comment about GoodHead's Cinnamon-flavored lubricant / pleasure enhancer for the administrator of oral sex: "It's like chewing Big Red and sucking...the best damn lube period!" Unfortunately, there are no more individual 4-ounce tubes of Cinnamon GoodHead left.
Because I bought all of them for my girlfriend.
However, you can get a 1-ounce sampler, along with similar tastes of 4 other GoodHead flavors, with this 5-pack of fruity, spicy, and minty facilitators of the blow job. Or I guess any other persuasion of oral sex that tickles your nipple. The package includes tubes of Cinnamon, Mint, Strawberry, Passion Fruit, and Cherry, and an overall 4-star review on Amazon. Individual reviewers prefer some flavors to others, but there doesn't seem to be a consensus on Best and Worst, so you'll have to give them all a whirl (and a swirl and a lick) and decide for yourself.
