This stainless steel urethral probe provides gradual urethral stimulation, increasing arousal and sensations as it is inserted.

It has graduated ridges that allow for progressive stretching, sending waves of pleasure through the centre of the penis. The hollow tunnel ensures space for lubricants and bodily fluids.

To prevent excessive insertion, simply pull the recovery ring to remove the rigid shaft from the shaft.

Before use, you can run hot or cold water over the sound for an extra experience with temperature variations, but extreme temperatures should be avoided so as not to damage the urethral tissue.

Generous use of sterilised lubricant and careful cleaning of the sound before and after use is recommended. Begin by gently separating the urethral opening and slowly sliding the tip of the shaft in, enjoying the stretching provided by the ridges.

During the experience, you can stroke the shaft to feel internal and external pressure simultaneously. To remove, pull the recovery ring and relax.

Measurements: total length 16.3 cm, insertable length 13 cm, maximum insertable diameter 1.2 cm, internal diameter 0.4 cm.
