Use & Care
- Choose your size: Measure the length of the erect penis from base to tip to help determine the appropriate Fat Boy sleeve length. Confirm fit using the manufacturer's sizing guidance.
- Before use: Inspect the sleeve and scrotum loop for tears, damage or deterioration. Ensure the material is clean.
- Lubrication: Apply a small amount of SilaSkin™-compatible personal lubricant to the interior if needed for comfortable positioning. Confirm lubricant compatibility with the manufacturer.
- Putting it on: Gently stretch the sleeve and position it over the penis. Carefully place the scrotum loop as intended without excessive tension or pulling.
- Adjusting comfort: Ensure the sleeve and scrotum loop fit comfortably without pinching, painful pressure or restricted circulation.
- Solo play: Explore the ribbed and ball-textured interior with gentle stroking movements, adjusting pressure and lubrication as needed.
- Partnered play: Use the smooth exterior for comfortable stimulation, starting slowly and communicating with your partner. The sleeve changes the effective size, so avoid forcing penetration.
- Removal: Gently release the scrotum loop and slide off the sleeve. Remove immediately if you experience pain, numbness, swelling, unusual colour changes or discomfort.
- Cleaning: Clean before and after use with a material-compatible intimate toy cleaner according to Perfect Fit's SilaSkin™ care instructions. Pay attention to the interior textures and scrotum loop.
