1. When I keep more than one doll, it’s usually a matter of having my main doll which is the one I always sleep next to at night, and any other are ones I bought to either see the doll quality of a certain company or see how they’ve improved if I bought from them before.
More curiosity than a want for a doll harem, since storing more than one doll also requires extra space and possibly more clothing depending on how different the doll’s sizes are.
2. I’m not interested in buying more of the same, but it’s very interesting to experiment with different types of dolls and figure out how you enjoy them and their pros and cons. My first was a WM140D, last year I tried mini-dolls of 68cm. You’ll probably notice quickly how addictive dolls can be. After you get some experience with your first, you’ll get a better idea about what you like and want for your next doll, and will eventually start browsing the stores again. It’s inevitable!
