In the traditional concept of marriage and love, "emotional exclusiveness" and "long-term commitment" are the core pillars. People generally believe that intimate relationships need to be based on two-way emotional contributions and responsibility. The emergence of new sex dolls is breaking this inherent cognition with their unique attributes - it is no longer a static product like a torso sex doll that only meets basic functions, but has the ability to intelligent interaction, emotional simulation, etc., and can provide users with a companionship experience similar to real people through functions such as voice response and temperature perception. This kind of companionship does not involve conflict mediation and family responsibility sharing in real marriages and love, but it can accurately meet some people's needs for "pressure-free intimate relationships", which has led some people to question the concept of "having happiness through two-way running-in" in traditional marriages and loves. For example, after some solitary groups use new sex dolls, they believe that they can not only provide emotional comfort, but also do not need to face quarrels and compromises in marriage and love. This "low cost and high satisfaction" experience has shaken the necessity of traditional marriage and love, and thus challenged the traditional perception that "marriage and love are the only way to obtain emotional companionship."
