Sex has been around since, well, since Adam and Eve and so have drinks and foods designed to give you that loving feeling. (That's right before there was Viagra there was raw turtle eggs!)
Here are a few well-know aphrodisiacs from the Caribbean. Check 'em out and let me know if they help!
1.) Raw turtle eggs.
2.) Guinness Stoutt mixed with milk.
3.) Goat-head soup.
4.) Pepper sauce.
5.) Cow-cod soup. (soup made from the penis and testicles of a bull)
6.) Peanut porridge.
8.) Fish-head soup.
9.) Coconut water.
10.) Linseed oil. (not clear whether you drink it or, um, apply it.)
11.) Bois bande. (a tea or liqueur made from the bark of a tree and also called maubi in some islands.)
So there you have it. I can't guarantee that any of the eleven will put the pepper in your sauce but try them when you're writing and who knows what heights of eroticism your stories might reach!
