At 3.5 inches long, no offense to any men of that size, I don't think this was for sexual pleasure. It would be just as easy to make something larger. But that size just barely even works as a dildo since you'd have to kind of pinch the end of it to insert it. Also, the second image there shows it on a similar little table with a cut fruit and a cup.
