Parasocial relationships refer to one-sided relationships in which a person develops a strong sense of connection, intimacy, or familiarity with someone they don’t know, most often celebrities or media personalities. These relationships exist only in the mind of the individual, who experiences a bond despite the lack of reciprocity.
Forming parasocial relationships is fine.
Fapping (masturbating) to nsfw content is fine (unless it is illegal or unethical).
But forming a parasocial relationship with someone you fap to feels like cheating if you are in a relationship and a poor substitute for a relationship if you are single.
There was an AMA on reddit last week from someone who managed DMs for OF models. Their job was basically to get people hooked and thinking that they had a real relationship with these models via DMs…when the people weren’t even talking to the actual models at all. I think that probably qualifies as despicable.
