SSND-THREADED13

For users who crave intense, threaded rib tactile feedback combined with secure seating, this sound offers an impressive 8.3 inches of insertable length. By combining a long, continuously threaded shaft with a smooth, wide-gauge base segment, this instrument provides spectacular stimulation through the anterior anatomy while establishing a secure, comfortable lock deep within the body.

Anatomical Mapping & Threaded Mechanics: 

• Guided Gatekeeper Entry: Begins with a short, rounded 12mm tapered tip designed to smoothly open the Meatus and initiate the stretch with minimal resistance.

• Threaded Spongy Stimulation: Transitions immediately into an 11.5mm diameter threaded design that continues for a full 13cm. This extended ribbed section delivers incredible, continuous tactile feedback along the entire length of the Spongy (Penile) Urethra.

• Membranous Sphincter Lock: The threading slowly enlarges into a 12mm ball before sloping down into a 9.5mm relief valley. This drop allows the narrowest, least flexible Membranous Urethra and external sphincter to relax and grip the sound securely.

• Smooth Prostatic Seating: Scales back up out of the valley into a final, smooth straight length measuring 13mm in diameter for the last 5cm. This solid, wide-gauge base segment rests beautifully within the wider, more distensible Prostatic Urethra for a deeply satisfying finish.

Anatomical Design & Shared Dimensions:

• Insertable Length: A satisfying 8.3” of fully usable insertable depth.

• Tip Profile: Features a gentle 12mm rounded taper.

• Threaded Shaft: 11.5mm diameter ribbed texture running for 13cm in length.

• Retention Valley: 12mm ball dropping to a 9.5mm localized relief zone.

• Smooth Base Segment: A final 13mm diameter smooth segment running for 5cm to complete the stretch.

👑 Bob's Choice Recommendations

• Experience Level: Intermediate-Advanced. The initial tip demands a 12mm stretch, and the threaded shaft sits at a more manageable 11.5mm, and the final smooth shaft segment reaches a full 13mm.

• The Prime Durometer Recommendation: Bob highly recommends ordering this model in our #10 (medium). This density provides the absolute best structural definition for the threaded layout, ensuring that the 11.5mm ribbed texture holds its distinct ridges for maximum stimulation, while the 9.5mm valley maintains excellent column strength as it passes through the external sphincter.

Color Options: #18 and #30 are available in pure translucent. #00-20, #00-50, and #10 base colors are translucent white and can be mixed with any standard color.
