A guide on how to use sex dolls safely?

The sex doll is made of elastic silicone and TPE material. There are no safety concerns when used correctly. Which misuse will hurt you?
Direct insertion without lubricating oil will cause injury. Use other slippery fluids or buy low-quality lubes, which may cause allergies. Do not pay attention to the angle and strength when using it, or someone breaks in when using it, causing emotional agitation and injury. Bringing the sex doll home:
