Quick answer
Choose the Leo if you want a straightforward, single-ended dildo with a moderate girth for solo or partner play. Choose the Nexus Senior if you need a double-ended toy that works with a harness for shared penetration or hands-free positioning.
Shape and sizing: what the numbers mean in use
The Leo measures 6.75 inches long and 1.5 inches wide, giving it a balanced profile that suits a wide range of users. The Nexus Senior has two distinct ends: a curved side at 5-1/4 inches by 1-1/4 inches and a straight side at 6 inches by 1-3/4 inches. That means the Nexus Senior offers two different experiences in one toy, while the Leo keeps things simple with a single, consistent shape.
If you are new to Original Formula toys, start by comparing these dimensions to a toy you already own. The Leo's 1.5-inch width is a middle-ground girth, while the Nexus Senior's straight side is notably thicker at 1-3/4 inches. The curved side is the slimmer option, which can be useful for beginners or for targeted stimulation.
Harness compatibility and positioning
The Nexus Senior is designed to work best with a harness for vigorous vaginal or anal penetration. Its ingenious arc helps ensure comfortable positioning, and the double-ended design allows for shared use. The Leo, by contrast, is a single-ended dildo without a flared base or harness compatibility mentioned in the catalog, so it is not intended for harness use.
If you already own a harness or plan to use one, the Nexus Senior is the more versatile choice. For solo play or handheld use, the Leo's simpler design may be easier to maneuver.
Firmness and material considerations
Both toys are made from Vixen Creations' Original Formula, a single-density 100% premium platinum silicone. This material is hypoallergenic, hygienic, phthalate-free, and boilable. The firm texture of the silicone provides firm penetration for both partners with the Nexus Senior, and the Leo shares the same firmness.
Because both toys are single-density, they offer a firm feel rather than a squishy one. If you prefer a softer toy, you may want to look at dual-density options. But for those who want reliable firmness for penetration, either toy delivers.
Trade-offs to weigh
- Versatility vs simplicity: The Nexus Senior offers two ends and harness compatibility, but its double-ended shape can be more cumbersome for solo handheld use. The Leo is simpler to handle but lacks harness options. Decide whether you prioritize versatility or ease of use.
- Girth range: The Nexus Senior's straight side is 1-3/4 inches wide, which is thicker than the Leo's 1.5 inches. The curved side is slimmer at 1-1/4 inches. The Leo sits in the middle at 1.5 inches. If you want a thicker toy, the Nexus Senior's straight side is the thickest option; if you want a slimmer option, the curved side is the thinnest.
- Harness use: The Nexus Senior works best with a harness for vigorous penetration. The Leo is not designed for harness use. If you plan to use a harness, the Nexus Senior is the clear choice.
