If exploring the urethra is your thing, you should indulge in the ultimate pleasure of these smooth probes. The urethra is lined with highly sensitive nerve endings that can be extremely pleasurable when stimulated. Additionally, deep urethral play is the only way to directly massage the prostate. This set of 4 twisted, extra-long probes features smooth, pointed tips for easy insertion. The flat, rounded head allows for safe and easy removal. These probes are made from super-soft, medical-grade, phthalate-free silicone and have an overall length of 30 cm for particularly deep exploration. They have an insertable length of 29.6 cm and 4 different diameters of 0.3 cm, 0.4 cm, 0.5 cm, and 0.6 cm. Always use a generous amount of sterile water-based lubricant and insert slowly and gradually for maximum pleasure.
