Strap-on size is the question everyone has and no one asks out loud. Let us save you the awkwardness.
The truth: there's no universally perfect size. There's the size that's right for you — your bodies, your desires, your experience level.
Length: Shorter Than You Think
The market is full of dildos at 18, 20, even 25 cm. In practice, most people hit their pleasure peak well before those lengths. For beginners: 13 to 16 cm (5–6.5 inches). That's exactly why our magnetic dildo comes in S (13 cm) and M (16 cm).
Girth: The Most Important Factor
When it comes to sensation, girth (diameter) often matters more than length — it's what creates that feeling of fullness. A diameter of 3.5 to 4.5 cm (1.4–1.8 inches) works well for most beginners. Our S is 3.8 cm, our M is 4.2 cm.
Shape: Curve and Texture
Curve: a slight upward curve targets the G-spot or prostate more naturally. A straight dildo gives more neutral, controlled stimulation.
Texture: ridges and ribbing add extra sensation. For a first time, a smooth dildo is more predictable.
