The existence of a full body sex doll will completely change the aura of private space. The 1:1 body shape makes it impossible to hide in a dark cabinet like traditional toys, and it must participate in life scenes as a "quasi-life". A user who lives alone described that when he was working overtime late at night, he caught a glimpse of a full body sex doll in the corner, which was gleaming with pearly luster in the moonlight. "The contradictory feeling of both comfort and horror is hard to describe." The size of the fat sex doll is more aggressive - when the user tries to move it, the heavy weight and the sound of the skin rubbing against the sheets remind the user that this is a space symbiosis that needs to be taken seriously.
