Quick Answer
To use the Nexus Simul8 Wave, start with lubrication, insert the shaft so the tip reaches your prostate, then activate the waving motion and perineum vibration. Adjust the cock and ball ring for a secure fit.
Why the Simul8 Wave Stands Out for Dual Stimulation
Unlike single-function massagers, the Nexus Simul8 Wave combines two independent motors: a waving tip that moves back and forth to target the prostate, and a vibrating base that stimulates the perineum. This design lets you experiment with different sensations without switching devices.
The integrated cock and ball ring is super-stretchy and helps maintain a firmer erection during use. This can be especially helpful if you find prostate play distracting or lose arousal easily.
Common Mistakes to Avoid
Skipping lubrication is the most frequent error. The Simul8 Wave is made of body-safe silicone, which requires a water-based lubricant to avoid friction and discomfort.
Another mistake is inserting the shaft too deeply before the tip aligns with the prostate. The waving motion works best when the tip is positioned against the prostate gland, about 2–3 inches inside the rectum.
Step-by-Step Instructions for the Nexus Simul8 Wave
- Prepare the Massager and Yourself: Charge the Simul8 Wave fully before first use. Apply a generous amount of water-based lubricant to the shaft, the perineum base, and the cock and ball ring. Clean your hands and consider emptying your bladder beforehand. Silicone toys need water-based lube only; oil or silicone lube can damage the material.
- Fit the Cock and Ball Ring: Stretch the super-stretchy ring over your penis and scrotum so it sits comfortably at the base. It should feel snug but not painful. Adjust it before insertion to avoid repositioning later. If the ring feels too tight, remove it and try a different angle; never force it.
- Insert the Shaft: Gently press the tip of the shaft into the anus. Angle it toward your navel to follow the rectal curve. Insert slowly until the perineum base rests against the skin between your scrotum and anus. The tip should now be near the prostate. If you feel sharp pain, stop and add more lube or try a different angle. Discomfort usually means insufficient lubrication or incorrect angle.
- Activate the Waving Tip: Press the button on the shaft to cycle through the 5 speeds of waving motion. Start at the lowest speed. The tip will move back and forth, massaging the prostate. Experiment with higher speeds as you become comfortable. The waving motion is subtle at low speeds; give it a few seconds to feel the effect before increasing speed.
- Add Perineum Vibration: Use the separate button on the base to turn on the 6-speed vibrating motor. You can run the wave and vibration simultaneously or independently. Try different combinations to find what works for you. If the vibration feels too intense, lower the speed rather than turning it off completely—the external stimulation often enhances the internal sensation.
- Experiment with Positions and Partner Use: Lying on your side with knees drawn up is a common starting position. You can also use the Simul8 Wave with a partner—the dual controls allow each person to adjust their preferred stimulation. The ring helps maintain erection during partnered play. For partnered use, communicate clearly about speed preferences. The remote-style controls make it easy to hand over adjustment to a partner.
