Sexuality encompasses a wide range of human expressions, and it is not limited to genital sexual activity. Non-sexual physical intimacy, such as hugging, cuddling, touching, gentle kissing, caressing, eye contact, or whispering, is also a vital part of this dimension.
Research in psychology indicates that non-sexual physical contact—such as massages, caresses, hugs, holding hands—is linked to higher levels of relationship satisfaction and better conflict resolution, according to studies by the Kinsey Institute and other sources ((https://blogs.iu.edu/kinseyinstitute/2020/05/28/the-power-of-touch-physical-affection-is-important-in-relationships-but-some-people-need-more-than-others)).
Proximity without physical contact, such as holding a gaze, can also generate feelings of emotional intimacy comparable to direct contact ((https://en.wikipedia.org/wiki/Physical_intimacy)).
Non-sexual physical affection enhances the release of oxytocin—the so-called bonding hormone—and reduces cortisol, creating a sense of emotional closeness, security, and relaxation ((https://www.psychologytoday.com/us/blog/mental-health-nerd/202408/how-non-sexual-physical-affection-enhances-sexual-connection)).
Non-sexual affection is also associated with physiological benefits: hugs, caresses or candid displays of affection contribute to stress reduction and improve general well-being, according to recent reviews based on multiple studies ((https://www.dailytelegraph.com.au/lifestyle/physical-touch-can-reduce-pain-and-depression-research-confirms)).
"Comforting touch," such as hugging or holding someone's hand in distress, triggers a release of oxytocin, dopamine, and serotonin, while decreasing cortisol; these effects tend to be greater if the person comforting is emotionally close (https://en.wikipedia.org/wiki/Consoling_touch).
Affection Exchange Theory (AET) explains that communicating affection is a biologically adaptive behavior that strengthens bonds, promotes mental health, and contributes to relational well-being ([(https://en.wikipedia.org/wiki/Affection_exchange_theory)).
If you're wondering whether you're being affectionate or receiving enough affection, keep in mind that everyday gestures—a spontaneous hug, a close look, a whisper in the ear, or holding hands—are essential expressions of intimacy that strengthen relationships, reduce stress, and promote emotional well-being. Recognizing a potential emotional void is a valuable first step, and opening a dialogue about your needs can make all the difference.
Sexuality, fully understood, goes beyond sex. The desire to cuddle, hug, gaze, touch, or whisper are profound expressions of affection that are fundamental to relationships. Scientific evidence supports their positive impact: they foster intimacy, reduce stress, increase well-being, and promote healthy behaviors. If you feel a lack of affection in your relationship, remember that it's these simple gestures that can strengthen the bond. Dare to express yourself, communicate with your partner, and value nonverbal forms of emotional connection.
