Study Reveals Why Sexting Strengthens Some Relationships but Strains Others

New psychological research suggests sexting itself is neither good nor bad for relationships, and that what really matters is why partners choose to do it. When people sext to deepen intimacy or share pleasure, they tend to feel more satisfied with their sex lives and relationships overall.

But when sexting is driven by fear, guilt or pressure, it is linked to lower sexual satisfaction and weaker relationship quality. The findings come from a two-part study published in The Journal of Sex Research that examined how motivations shape the impact of technology-mediated sexual interactions.

The study, titled “It’s Not What You Do, it’s Why: Motives and Outcomes of Technology-Mediated Sexual Interactions in Romantic Relationships,” highlights that digital intimacy is now a regular part of many couples’ lives. Understanding these motivations may help partners use digital intimacy in ways that strengthen, rather than strain, their relationship.

What counts as digital sexual activity

Researchers use the term technology-mediated sexual interactions to describe sharing self-created sexual material via digital devices. This includes sexually explicit text messages, intimate photos or videos, and spoken exchanges such as phone sex between romantic partners.

Many couples use these tools to stay connected, particularly when separated by distance or busy schedules. Earlier studies have shown mixed results, with some linking sexting to greater happiness and others associating it with conflict and negative emotions.

Lead author Erin Leigh Courtice, a postdoctoral researcher at Toronto Metropolitan University, suspected the contradictions came from overlooking people’s underlying motives. Her team turned to an established psychological model known as the approach-avoidance motivational framework.

Approach versus avoidance motives

According to this framework, people engage in behavior either to move toward positive outcomes or to avoid negative ones. In sexual contexts, approach motives could include seeking pleasure, closeness or excitement with a partner.

Avoidance motives, by contrast, involve trying to escape conflict, rejection or criticism. For example, someone might sext to prevent an argument, appease a demanding partner or sidestep in-person sex they do not really want at that moment.

This model has been widely studied in offline sexual behavior but rarely applied to digital intimacy. The new research aimed to test whether the same patterns hold when sexual communication happens through phones and computers rather than face to face.

Study one: building a new measure

In the first study, the team surveyed 269 university students in committed relationships, with an average age of 19. Around 40 percent reported being in long-distance relationships, where digital communication often plays a larger role.

Because no standard questionnaire existed for motives behind digital sexual exchanges, the researchers developed their own scale. They adapted items from tools used in in-person sex research and added questions specific to texting, photos and other online interactions.

Analysis showed that participants’ reasons for engaging in technology-mediated sexual interactions fell into three main groups: approach motives, avoidance motives and affirmation motives focused on seeking reassurance about one’s physical attractiveness.

Courtice noted that some people clearly used sexting to feel more desirable or receive feedback about their bodies. The study did not deeply explore how these affirmation motives relate to satisfaction, but the authors see this as an important avenue for future research.

The first study also found that people distinguished between their satisfaction with digital sexual exchanges and their satisfaction with in-person sex. Likewise, their desire for digital intimacy was separate from their desire for physical contact, suggesting these are distinct aspects of romantic life.

Study two: motivations and well-being

The second study included 459 adults in committed relationships with an average age of 30, recruited from both online platforms and university pools. All participants had engaged in some form of technology-mediated sexual interaction with their partner.

They completed the refined motives questionnaire along with measures of life satisfaction, relationship satisfaction and the frequency of their digital sexual activity. The team initially predicted that avoidance motives would be linked to less frequent sexting.

However, the data showed the opposite pattern: higher avoidance motives were actually associated with more frequent technology-mediated sexual interactions. Courtice suggested that if sexting successfully averts conflict or a breakup, it can reinforce both the behavior and the fearful motive.

This means that even when digital sexual exchanges are used defensively, they can become a regular part of the relationship. Yet the emotional consequences of approach and avoidance motives were very different, even at similar levels of activity.

How motives shape satisfaction

People who reported sexting mostly for approach reasons, such as enhancing intimacy, fun or anticipation of in-person sex, tended to feel more satisfied. They reported higher satisfaction with their digital sexual life, their offline sex life and their relationship in general.

Those who more often sexted for avoidance reasons showed a different pattern. Engaging to appease a partner, manage negative emotions, prevent conflict or avoid in-person sex was linked to lower in-person sexual satisfaction and lower relationship satisfaction.

Across both groups, the pathway appeared to run through desire for one’s partner. Approach motives predicted stronger dyadic sexual desire, which in turn was associated with higher sexual, relationship and even life satisfaction.

Avoidance motives predicted weaker desire for a partner, and that reduced desire was tied to poorer outcomes. Still, the influence of sexting motives on overall life satisfaction was modest compared with their impact on sexual and relationship domains.

How much does sexting really matter?

When the researchers calculated effect sizes, they found the strongest links between motives and technology-specific outcomes. Approach motives were strongly tied to satisfaction with digital sexual exchanges and desire for more of them.

As the measures moved away from digital sex into broader life domains, the effects became weaker. Motives and desire together explained about 35 percent of the variation in in-person sexual satisfaction and 27 percent in relationship satisfaction, but only 8 percent in life satisfaction.

This suggests that while sexting motives meaningfully shape how people feel about their sex lives and partnerships, they account for only a small share of differences in overall well-being. Many other factors clearly influence how happy people feel day to day.

The authors also stressed that their research was cross-sectional, capturing data at a single point in time. That makes it impossible to prove whether avoidance motives harm relationships or whether existing problems drive people toward more defensive sexting.

Limits and key takeaways

The study focused only on people who were already sexting within a committed relationship, so it cannot determine whether couples should start. It also does not address non-consensual sharing of images or coercive digital behavior, which raise separate ethical and legal concerns.

Instead, the findings refine the basic question of whether sexting is good or bad for couples. Courtice argues that the more accurate question is why partners are engaging in it and how those motives interact with their existing relationship dynamics.

For individuals, the work suggests a practical self-check before sending an intimate message. If sexting is driven by curiosity, connection or mutual pleasure, it is more likely to support satisfaction, while fear-based motives may signal deeper issues that need to be addressed.
