A record number of Japanese teenagers have never kissed. Researchers asked teens about their sexual behaviour. The study found that one in five high school boys and one in four girls have kissed. These are the lowest figures since records began in 1974. The numbers for boys and girls have been falling since 2005.

A reason why high schoolers are not kissing is the coronavirus pandemic. Teenagers had less contact with other people. It may have lowered sexual activity. A researcher said there was less face-to-face contact. Another reason is smartphones. More young people are choosing to be with their phones rather than be with other people.
