Anal toys are adult products specifically designed for safe and pleasurable anal stimulation. Common types include butt plugs, prostate massagers, and anal beads. Their design prioritizes safety, comfort, and anatomical compatibility. Below are their essential characteristics:

1. Safety-Focused Structure

• Tapered, gradual tip: Allows for smooth, comfortable insertion.
• Narrow neck: Helps the toy stay in place comfortably while ensuring it can be easily removed.
• Flared base (wide bottom): This is the most critical safety feature—it prevents the toy from being accidentally pulled fully into the rectum, making retrieval safe and reliable. All anal toys must have this feature.

2. Ergonomic Sizing and Curvature

• Available in a range of sizes—from beginner-friendly (diameter ~2–3 cm / 0.8–1.2 in, length 8–10 cm / 3–4 in) to advanced options (diameter 4+ cm / 1.6+ in).
• Some toys feature a precise upward curve， designs often focus on overall comfort and indirect G-spot stimulation.

3. Body-Safe, High-Quality Materials

• Common materials include:
  • Medical-grade silicone: soft, non-porous, hypoallergenic, and easy to sterilize—considered the gold standard.
  • ABS plastic: firm and smooth, ideal for users who prefer rigid stimulation.
  • Stainless steel or borosilicate glass: compatible with temperature play (can be warmed or cooled), though require careful handling.
• Reputable products are phthalate-free and comply with international safety certifications (e.g., CE, RoHS).

4. Seamless, Ultra-Smooth Surface

• Highly polished with no seams, ridges, or rough edges to minimize friction and reduce the risk of tissue irritation or injury.

5. Varied Functionality (by model)

• Non-vibrating: Relies on shape, texture, and manual movement for natural stimulation.
• Vibrating models: Feature quiet motors with multiple intensity levels and patterns for enhanced sensation (must still include a secure flared base and sealed electronics).
• Wearable designs: Some butt plugs include O-rings or harness-compatible bases for use with strapon systems.

6. Easy to Clean and Maintain

• Non-porous materials (silicone, glass, metal) can be washed with warm water and soap, boiled, or sanitized with toy cleaner.
• Semi-porous materials (like TPE) should be gently hand-washed and stored separately; avoid using silicone-based lubricants with them.

7. Requires Lubricant for Safe Use

• The anus does not self-lubricate, so generous use of lubricant is essential.
• Water-based lubricants are recommended for all anal play. If using a silicone toy, avoid silicone-based lubes, as they can degrade the material over time.
