As someone who sells surreal adult sex dolls, I'm often asked if it's possible to develop real feelings, or even an obsession, with such dolls. In my experience, the answer is: no. From a seller's perspective, there are several considerations:
Personalization. Sex dolls can be tailored to your preferences and become the embodiment of the woman of your dreams. A personalized appearance and behavior that matches your preferences can create an emotional bond. The more a doll matches your ideal image of your partner, the more likely you are to become emotionally attached and bond with it. Some manufacturers specialize in using this in their marketing.
Surrealism creates intimacy. Extremely realistic sex dolls have perfect anatomy, natural facial expressions and skin structures that mimic realism in an impressive way. This can lead to the doll's emotions being absorbed, at least temporarily. Vivid illusions allow real and virtual encounters to blend together. Aspects such as body temperature or automatic movement options help to reinforce the immersion.
Relationship Projection. Many customers see their sex doll as more than just a sex object, giving it its own personality and ability to connect. You establish an imaginary relationship with the doll. Even if this isn't reality, for some people it feels like a real emotional connection. Personalizing the big butt sex doll to your own ideas can facilitate this process. Knowledge of their artificiality fades into the background.
Idealization of the partner. A sex doll can be seen as an idealized version of a romantic partner. She is always on call, has no needs or demands of her own, and does not force compromise. This perfect predictability and obedience to the user's desires makes puppetry more appealing to some than an unpredictable relationship with a real, flesh-and-blood human being. Idealization inspires emotional passion.
However, many of my clients show signs of emotional attachment, projection, and idealization of their blonde sex dolls that come close to this. It comes down to each individual's sense of reality and need for relationships.
