The \u003cstrong\u003elong version\u003c\/strong\u003e provides a tighter internal fit and more intense stimulation throughout the shaft. Both versions feature the same dual-channel touch-point lining and locking testicle ring. If you are new to cock sleeves, the short version is the recommended starting point.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWill the Muscle-Flex sleeve fit my size?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eYes. The platinum silicone used in this sleeve has exceptional Muscle-Flex elasticity, meaning it stretches comfortably to accommodate a wide range of girths without losing shape. The ergonomic curved design also ensures there is no pinching or pressure at the base or tip. \u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWhat does dual-channel stimulation mean?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe inner channel of the Muscle-Flex sleeve is lined with raised touch-point texture nodes. As you move, these nodes create a consistent, layered stimulation for the wearer — separate from the sensation your partner experiences. The result is a dual-channel effect where both partners receive enhanced stimulation simultaneously, rather than the sleeve simply adding girth for one side only.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eHow does the locking testicle ring help with stamina?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe stretchy ring at the base of the sleeve wraps around the testicles and applies gentle, consistent restriction. This slows blood flow just enough to help maintain firmness and delay climax, extending the duration of intercourse without any discomfort. It stays in place throughout without requiring adjustment.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eHow do I clean the Muscle-Flex sleeve?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eRinse thoroughly with warm water and a mild toy cleaner after each use. The non-porous platinum silicone surface does not harbour bacteria and is fully waterproof, so it can be rinsed under running water without concern. Allow to air dry completely before storing in a cool, dry place away from direct sunlight.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eIs the packaging discreet?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eYes.
