Sex blankets and sheets are designed to protect bedding and furniture from fluids during sexual activity. These products are typically waterproof, easy to clean, and made from soft, comfortable materials that feel good against the skin. They are a practical solution for those who want to be adventurous and messy without worrying about the cleanup, allowing for more spontaneous and uninhibited play. They are available in various sizes and styles, from discreet throws to fitted sheets.
