(Wikipedia) Object sexuality or objectum sexuality, in German objektophile (OS),  is a pronounced emotional and often romantic desire towards developing significant relationships with particular inanimate objects. Those individuals with this expressed preference may feel strong feelings of attraction, love, and commitment to certain items or structures of their fixation.
For some, sexual or even close emotional relationships with humans are incomprehensible. Object-sexual individuals also often believe in animism, and sense reciprocation based on the belief that objects have souls, intelligence, feelings, and are able to communicate.
This is contrary to sexual fetishism where the object is not viewed as the partner but a means to an end to enhance a human sexual relationship.
