Abstract
In contemporary Japanese society, a decline in sexual interest and activity among young people has been noted. At the same time, in social VR—a type of metaverse—particularly within VRChat, where young users comprise the majority, there is a growing discourse suggesting that virtual sex is becoming established as a cultural phenomenon. This presentation tries to grasp the reality of virtual sex among young people based on the results of a web questionnaire conducted in the Japanese community of VRChat. As a result, the following were clarified. (1)Biological men have had the majority of realworld sex as well as virtual sex in VRChat, whereas biological women have had significantly higher rates of real-world sex and significantly lower rates of virtual sex in VRChat than biological men. (2)A certain number of people have experienced virtual sex on VRChat but have never had sex in the real world. (3)For biological men, many virtual sex experiences with non-opposite-sex individuals were identified, regardless of sexual orientation or whether they were role-playing as the opposite sex.
