Vibrating Cock Rings
Don't take your vibrating cock ring for granted! In 4004 B.C., when the first caveman tied a length of velociraptor gut around his scrotum and went off to give the first cavewoman the first cock-ring assisted boning, how could he have dreamed that only six short millennia later, the technology would have advanced to the point where his messy, improvised erection aid would be a vibrating, latex wonder of science? Nowadays, tiny motors and space-age polymers make it possible for not just hunters but gatherers to possess the finest in cock-ring technology -- stretchy, vibrating, textured erection enhancers for everyone on the food chain!
