Another recent inspiration, Habanero Flavored Personal Lubricant. Marketed with such phrases as "Some Like it Hot" and "Put the Spice back into Your Sex Life" and "Spice it Up". Discreetly packaged in squirt bottles so it can be sold in supermarkets and drugstores, alongside the cherry and other flavored lubricants, with perhaps flames and habanero peppers on the label, which would attract potential customers because, really, everyone likes to feel like their being a little naughty and going to hell when they have sex. And with my Habanero Flavored Personal Lubricant, those feelings will not just be psychological...
I'm thinking there will be a pretty big market for this, but I'm not really into cooking up sexual lubricants in my kitchen (although if I were I'd be sure to write "small batch" on the label, because then I could charge higher prices for it). But if you work for a company that manufactures similar things and stumble across this post, feel free to use my idea, we'll work out the royalties later.
