Among the benefits of living in the digital age is that two people can "do it" anytime, via cell phones or the Internet.

Sex messages, or in English known as "sexting", also include sending sex videos and photos.

Many couples do this, but researchers Rob Weisskirch, Michelle Drouin and Rakel Delevi have decided to look deeper into why people send these messages and what this says about their relationship, Telegraph reports.

Specifically, the researchers are interested in learning how relationship anxiety factors into decisions to send such messages.

Is this coming from a place of comfort, or fear?

To get a better idea of ​​their motives, they gave 459 unmarried heterosexual college students an online survey that measured “their sexting behaviors, the connection commitment needed to participate in conversations such, their fear of remaining single, etc."

It appears that people in romantic relationships, regardless of how long the relationship was, were more likely to send such messages than those who admitted to being single.

In addition, if someone was afraid of the partner's negative evaluations, but had been safely close to them, then they also had the opportunity to exchange sex messages.

Basically, this means that people who are comfortable with their relationships feel safe to be intimate even through texting.

This fact is against the initial hypothesis of the researchers, who at first guessed that the exchange of messages, photos and sex videos comes as a result of the fear of losing the relationship, when in fact it turns out to be a symptom of a happy and healthy relationship.
