It is important to distinguish between sexual aids and emotional betrayal. Many couples accept masturbation as a private, individual act that does not threaten the bond of the relationship. Sex toys are widely normalized, and their use does not automatically signal infidelity. A small breast sex doll could be viewed as an extension of this category—a more elaborate tool rather than a rival. From this perspective, the absence of another conscious human means there is no divided loyalty, no romantic secrecy, and no violation of exclusivity. The act remains solitary, even if the object appears human-like.
