Osyters and an Attempt at the Logic of Aphrodisiacs

I used to be 'scared' of oysters when I was young. Scared, in a way that they looked strange to me, and that I didn't know how to shuck them. I didn't eat oysters until I was in my mid- twenties. (Whatever happened to me?) True, I lived in a province known for fantastic seafood but we had our own shellfish there and that didn't include oysters. When I lived with my siblings at our apartment and all sorts of food were introduced, oysters came in shells smelling of the sea. Shucking and cooking were done at our small sink, and there oysters went to various dishes from ceviche to fried. I am not fond of ceviches. Imaginary indigestion and food poisoning brought by paranoia made the acidulated food even more unappealing. But I LOVE (luuurve) fried oysters.

Oysters, like mussels, are good aphrodisiacs, it turned out. I have to see yet how aphrodisiacs work in real life. Does one get that love flush and make one more attractive to his mate? Do hormones rage at one thousand bytes per second that hitting the sack is the next best thing to dessert?
Studies say that there's a mineral in oysters and some shellfish that aids in the development of sexual characteristics and better functioning of hormones. That mineral is called zinc. I guess, if we connect the dotted logic of oysters:

A. Oysters are known aphrodisiacs --> B.Aphrodisiacs enhance sexual drive --> C.  Zinc aids in sexual functioning and drive--> D. Oysters contain zinc ---> Ergo, Oysters are Aphrodisiacs. (A+B+C+D= E) ???

I flunked logic in college.
