The oldest sex toy in the world—a siltstone phallus—was discovered in Germany and is said to have also been used as a tool to start fires, the New York Daily News reported.

The approximately 30,000-year-old artifact was found in more than a dozen pieces inside a cave and was later put back together by scientists at Germany’s University of Tubingen.

The prehistoric object features carved rings around one polished end, in addition to indented areas on the tool where it was struck against flints to ignite fires.

Scientists said artifacts displaying masculinity weren’t common during this time, making the sex toy discovery an unusual find.
