In　this　chapter,　we　described　pornography　use　motivation　and　prevalence　in　Chinese　men　and　women,　and　screening　scales　for　PPU.　More　than　50%　percent　women　reported　use　of　porn.　As　for　types　of　online　sexual　activities,　the　largest　gender　difference　was　observed　in　“found　sexual　partners　online”　and　the　smallest　difference　in　“flirting　and　maintaining　a　relationship.”　During　the　COVID-19　pandemic,　people’s　porn　use　motivations　were　stress　reduction,　selfexploration,　and　fantasy,　but　men　had　a　stronger　motivation　to　use　porn　than　women.　Although　existing　PPU　screening　scales　weren’t　originally　developed　in　Chinese　samples,　several　scales　were　confirmed　valid　for　Chinese　women.　©　2023　selection　and　editorial　matter,　Fulvia　Prever,　Gretchen　Blycker,　and　Laura　Brandt;　individual　chapters,　the　contributors.
