One of the first forks in the road when browsing dildos is realistic versus non-realistic design. Realistic options mimic anatomy closely, often with veins, a defined head, and a flesh-like texture — great if that visual and tactile familiarity appeals to you. Non-realistic designs range from simple smooth curves to bold, colourful, sculptural shapes, and tend to focus purely on the angle and texture that feels best rather than looking like anything in particular.
Neither is objectively better; it really comes down to personal preference and what you’re using it for. Curved designs are popular for targeting specific internal areas, while straight, simple shapes are often easier to control for beginners.
If you’re not sure yet, a mid-firmness silicone option in a moderate size is usually the safest starting point — you can always build a collection once you know what you gravitate toward.
