No need to be embarrassed...
If you had clicked on the link I posted you would have read about this very thing.
I'll post the paragraph that discusses it.
This site is from the FDA so I'd say it's fairly reliable from a medical standpoint.
Welcome to the Club, Jane....LOL

"Many ancient peoples believed in the so-called "law of similarity," reasoning that an object resembling genitalia may possess sexual powers. Ginseng, rhinoceros horn, and oysters are three classical examples.
The word ginseng means "man root," and the plant's reputation as an aphrodisiac probably arises from its marked similarity to the human body. Ginseng has been looked on as an invigorating and rejuvenating agent for centuries in China, Tibet, Korea, Indochina, and India. The root may have a mild stimulant action, like coffee. There have been some experiments reporting a sexual response in animals treated with ginseng, but there is no evidence that ginseng has an effect on human sexuality.
The similarity of the shape of the rhinoceros horn to the penis is credited for its worldwide reputation as a libido enhancer. The horn contains significant amounts of calcium and phosphorus. The addition of the food to a deficient diet could improve general physical vigor and possibly lead to an increased sexual interest. But in most Americans' diets, which are usually not lacking calcium or phosphorus, the small quantities usually consumed would not affect physical performance.
Because Aphrodite was said to be born from the sea, many types of seafood have reputations as aphrodisiacs. Oysters are particularly esteemed as sex aids, possibly gaining their reputation at a time when their contribution of zinc to the nutritionally deficient diets of the day could improve overall health and so lead to an increased sex drive."
