A study has showed that couples who send each other sexually suggestive or explicit images by phone enjoy sex much more than their counterparts who do not. Sexting is a term commonly used for the practice of sending sexually suggestive images.

The practice is said to be risky, but it’s widespread and a good means of improving communication and in increasing intimacy among couples.

Emily Stasko of Philadelphia's Drexel University said the findings of the study, presented to a psychology convention in Toronto, have provided strong evidence that sexting is linked to sexual relationship satisfaction.

The results of an online survey of 870 Americans aged 18 to 82 were presented at the American Psychological Association's 123rd Annual Convention in Toronto on Saturday.

The survey results showed that more than eight out of 10 respondents sexted. Images were sent by 75% of them to a boyfriend, girlfriend, husband or wife. They said that sexting helped them achieve better relationship satisfaction.

Past studies have portrayed sexting as a bad habit, despite its potential to enhance communication between partners.

US lawmaker Anthony Weiner left the House of Representatives after he was alleged for sending sexually explicit pictures of himself to a number of women on social media. In another sexting case last year, nude photos of celebrities including actress Jennifer Lawrence, pop icon Rihanna and top model Kate Upton were leaked after phone hacks.

“People who are in a good relationship, who have good sex, don’t need to find other venues to turn each other on. They are turned on, but the people in the in between phase need some extra help”, said Dr. Judy Kurianksy.
