Quick answer

Choose the Small Fornax 4.0 if you're new to larger toys or prefer a softer, more manageable shape. Pick the Medium Fornax 4.0 if you have experience with girth and length and want a more filling feel.

Why size and firmness matter together

The Fornax 4.0 is a tapered fantasy toy with a pronounced head and a widening shaft. The Small version offers a gentler learning curve, while the Medium adds significant length and girth. Firmness also plays a role: a soft silicone can make a larger toy feel more forgiving, while a medium silicone gives more texture feedback. Your experience level and comfort with girth should guide your choice.

How to choose between Small and Medium Fornax 4.0

  1. Step 1: Measure your current comfort zone: Measure the circumference or diameter of toys you already use comfortably. If you're fine with a shaft diameter of 1.5 inches or less, the Small Fornax 4.0 is a safe start. If you're ready for 1.75–2 inches, consider the Medium. Common mistake: Guessing instead of measuring. Use a soft tape or string to avoid overestimating your size tolerance.
  2. Step 2: Compare useable length: The Small has a useable length of 5.5 inches, while the Medium offers 6.5 inches. If you prefer a toy that doesn't require deep insertion to feel filling, the Small may be more comfortable. If you want more length for varied positions, the Medium gives extra reach. Checkpoint: The Medium's extra inch of useable length can make it less maneuverable for beginners.
  3. Step 3: Decide on firmness based on your sensitivity: The Small is available in medium silicone (0050), which provides more texture and a firmer feel. The Medium is available in soft silicone (0030), which is squishier and more forgiving. If you are sensitive to pressure, the soft Medium may feel better despite its larger size. Common mistake: Assuming a larger size always requires more firmness. Softer silicone can make a bigger toy feel gentler.
  4. Step 4: Consider your experience with tapered shapes: The Fornax 4.0 has a bulbous head that leads to a wider shaft. The Small's taper is more gradual, making it easier to navigate. The Medium's larger head and shaft demand more control. If you're new to this shape, start with the Small. Checkpoint: If you already own a similar tapered toy, compare its widest point to the Fornax 4.0 specs to avoid an uncomfortable surprise.
  5. Step 5: Match the toy to your goals: If you want a toy for warm-up or shorter sessions, the Small Fornax 4.0 is versatile and less intense. If you want a more filling, longer-lasting experience, the Medium provides that without being extreme. Empty
