Soloflesh operates on the principle of pressure rather than "tightness", a different approach than other male sex toys. Pressure from the outside walls, transmitted through warm water to the walls of the inner canal creates a snug fit. The inner canal adjusts to your size and shape, just as a woman does. The result is the feeling of gentle, natural pressure and warmth that envelopes you evenly and completely. The inner canal is free-floating. It expands, contracts, and shifts with your angle and depth of penetration, making the inside feel alive and real.
