How can one avoid contracting infectious diseases when using sex dolls?

First, it is essential to clarify the fundamental premise: sex dolls themselves are inanimate objects and do not inherently carry infectious disease pathogens. However, improper cleaning, storage, or usage during their operation may foster bacterial or fungal growth, or indirectly transmit pathogens associated with sexually transmitted diseases.

Furthermore, the use of such items carries risks of violating public order and good morals, and certain sales practices may involve illegal activities. The following analysis focuses solely on health protection aspects while advocating compliance with legal and social ethical standards.

一. Core Sources of Infectious Disease Transmission

Residual secretions or bodily fluids on contact surfaces, combined with delayed cleaning, can foster bacterial or fungal growth, leading to skin or mucosal infections. When shared among multiple users, pathogens from different individuals may be indirectly cross-transmitted via the doll, potentially facilitating the spread of STIs such as syphilis, gonorrhea, or genital herpes.

Substandard materials are prone to damage, mold growth, or contain harmful chemicals that irritate skin and mucous membranes, causing inflammation, reducing local resistance, and increasing infection risk. Damp, poorly ventilated storage environments become breeding grounds for microorganisms, leading to infection upon direct contact during reuse.

二. Core Preventive Measures

Before Use: Source Control

Select compliant products. Purchase only from reputable brands labeled “medical-grade silicone” or “food-grade TPE.” Reject unlabeled products to avoid damage and contamination risks from inferior materials. Thoroughly disinfect contact areas by evenly wiping with 75% medical alcohol or specialized adult product disinfectant, focusing on crevices and folds. Allow to sit for 5-10 minutes before drying with sterile gauze to ensure no disinfectant residue remains. Inspect skin condition. If hands or genital areas exhibit wounds, ulcers, eczema, or other breaks in the skin, suspend use to prevent pathogens from entering through damaged areas.

During Use: Isolation Protection

Wear condoms from reputable manufacturers throughout use to minimize direct skin/mucous membrane contact with the doll. This prevents secretion residue, reduces infection risk, and simplifies post-use cleaning. Avoid damaging the doll’s material during use. Immediately discontinue use if tears or breaks occur to prevent pathogens from accumulating in hard-to-clean damaged areas.

After Use: Thorough Cleaning and Storage

Immediately rinse contact areas with warm water to remove residual secretions. Disinfect thoroughly with a sterilizing agent, ensuring no areas are missed. Allow to air dry naturally or pat dry with sterile gauze. Never store in a damp state. Store separately in a dry, well-ventilated, clean environment using a dedicated sealed storage box. Avoid mixing with other items to prevent dust and bacteria accumulation. During prolonged non-use, periodically inspect for mold growth or damage. Discard immediately if any issues are found.
