You can interact with the doll depending on the needs.

The personality of the doll can already be in mind from the beginning, or a personal encounter may be necessary to give body to the character. The point is that everything related to the doll, from appearance to personality, it comes to you. That's what you want. It is difficult to find a real person who is fully compatible with your needs. Always compromise it is, not realistic sex doll. Perhaps "selfish" is not the right word, but I hope you understand what I mean.
