Discover how the Nexus Ultra Si combines firm polypropylene, soft silicone, and a stainless steel rollerball for dual prostate and perineum stimulation.
Quick Answer
The Nexus Ultra Si is a dual-action prostate massager that pairs a firm polypropylene core with a soft silicone exterior and a stainless steel rollerball for combined internal and perineum stimulation.
Why Dual Stimulation Matters
Many prostate massagers focus only on internal pressure, but the Ultra Si also targets the perineum—the area between the scrotum and anus. This external stimulation can enhance the overall sensation and may help some users achieve more satisfying results.
The combination of a firm shaft for precise internal massage and a rolling external element means you get two types of stimulation in one session, which can be more efficient than using separate products.
Material Trade-Offs: Firmness vs. Comfort
The Ultra Si uses a polypropylene core for structure and a silicone outer layer for a softer feel. This gives you the precision of a firm toy without sacrificing comfort on insertion.
Silicone is body-safe, non-porous, and easy to clean, but it requires a quality water-based lubricant. Avoid silicone-based lubes, as they can degrade the material over time.
Nexus Ultra Si FAQ
- How do I use the Ultra Si?
- Apply a generous amount of water-based lubricant to the shaft and rollerball. Insert slowly, angling the shaft toward the front of your body to reach the prostate. Use the rollerball externally against the perineum for added stimulation. Start with gentle pressure and increase as you become comfortable.
- Can I use it in the shower?
- Yes, the Ultra Si is waterproof, making it suitable for shower or bath use. Just ensure you clean it thoroughly afterward. Always dry the toy completely before storing.
- How do I clean it?
- Wash with warm water and mild soap or a dedicated toy cleaner. Avoid boiling or using harsh chemicals, as they can damage the silicone. Clean before and after each use to maintain hygiene.
- Is the rollerball removable?
- The rollerball is fixed in place but designed to rotate freely. Do not attempt to remove it, as this could damage the toy. If you notice resistance, add more lubricant to the rollerball area.
- What lubricant should I use?
- Use a water-based lubricant only. Silicone-based lubricants can break down the silicone surface over time. Reapply lubricant as needed during use.
