Public display of affection
Physical affection has been defined as, "any touch intended to arouse feelings of love in the giver and/or the recipient."
Effects on romantic relationships
Various studies have found physical affection to be associated with positive outcomes in romantic relationships. For instance, it has been related to the formation of attachment bonds and psychological intimacy Physical affection has been categorized into seven different types including holding hands, cuddling/holding, backrubs/massages, caressing/stroking, kissing on the face, hugging, and kissing on the lips. Five of these behaviors, with the exception of caressing/stroking and holding hands, have been significantly positively associated with relationship and partner satisfaction.
Social media
Expression of a person’s feelings towards someone else had previously been limited to written letters, phone calls, or in person. In the modern world, social media sites such as Facebook and Twitter are growing, with 1.3 billion users on Facebook and over half a billion Twitter users. However, many people now feel uncomfortable or irritated seeing public displays of affection through social media. Studies on relationships through Facebook found that, when two individuals who are interested in one another both use Facebook regularly, their relationship progresses in different increments than how it would without social media. After two people meet and form an interest, one or both individuals will go onto the other person’s Facebook page and get information such as relationship status, pictures, and interests. Once a relationship begins, some couples broadcast their relationship with posts, such as pictures and changing the relationship status.
