A survey by a government-backed information technology security agency has found that around 10 percent of those in their 20s who use smartphones or other smart devices did not mind using social media to share intimate photos with their romantic partners.

The survey, released Thursday by Information-technology Promotion Agency (IPA) Japan, showed that 7.4 percent of the users said it was fine to share their sexually explicit photos or videos online with people close to them, such as their partners.

By age group, those in their 20s accounted for 11.3 percent of the total willing to share such photos, the multiple response survey showed.
