Urethral play can be safe and pleasurable when done correctly, but precautions are necessary to prevent injury or infection. Always use high-quality, body-safe materials like surgical-grade stainless steel and apply plenty of sterile, water-based lubricant to reduce friction. Go slowly, never force insertion, and always sterilize your toys before and after use. Start with smaller, thinner sizes and gradually work up to avoid discomfort. If you experience pain, bleeding, or discomfort, stop immediately and seek medical advice if needed.
