You're actually correct lol the oldest recorded dildo found (I think like 26,000-28,000 years ago) was made of siltstone. I think the worst thing I have learned when I researched these things a while ago is that many civilizations used wooden dildos...my whole body seized up
Lmao
The splinters
im not versed in this specific topic but i do know about wood if its sanded and painted with lacquer or a protective finish i dont think splinters would be common,
what i would worry about is its not hygienic
You gotta wonder, was it the rock dildo or the plastic dildo that came first.
Probably the rock, if so.. the person who first made it.. how desperate were they and was it the stone age?
