Not sure if it's the collector's mentality in me but whenever I browse through onahole sites and see a product that i like and find out there is a series of them I tend to want to get all of them. Like them tenga eggs, looking at one just make me want to buy the whole set to try them out or just collect them lol. I'm talking about different variation of the products not the ones with the same product but different softness. Anyone have the same problem?
