I don't want spices and flavors to help turn my gf on and vice versa. Cinnamon seems too messy to be used as a aphrodisiac as well. On the rare occasion when I do, I use the classic all American whipped cream. It's your right as a American to do that, but in my household cinnamon is used only for pies.

Hmmmmm. See, my wife loves my hot chocolate, one of the secrets being that I always put a little cinnamon in it. Little did she know that I was lacing her drink with an aphrodesiac. Bwahahahahahahahahahaha!!! (that was my evil laugh)
