What does the ribbed nub at the base do? Most dildos only stimulate internally. This one has a small ribbed nub just above the base. When the dildo is fully inserted, the nub rests against the outside of the body, where it can rub the clitoris or the perineum depending on how you are using it. It is a subtle addition, not a second arm like a rabbit vibrator has. It gives you something to grind against at full depth.
Ribbed Rainbow dildo: texture inside, a nub outside
The Simply Sweet Ribbed Rainbow is a shimmering, multicolored silicone dildo with ribs running along the shaft. The tip is rounded and curved to reach the G-spot, the A-spot or the prostate. It is 6.6 inches long, with 6 inches insertable and a widest insertable diameter of 1.3 inches, and it is soft and flexible.
Near the base sits a small ribbed nub for clitoral or perineal contact once the dildo is all the way in. The base is wide, has a strong suction cup and fits most strap-on harnesses. The silicone is non-porous, phthalate-free and latex-free.
Best for: Suited to beginners and experienced users who like texture. The slim 1.3 inch diameter and soft flex make it approachable, and the ribs keep it interesting. Use it by hand, stuck to a flat surface, or in a harness for pegging and other strap-on play.

How to use
Wash the dildo with warm water and mild soap before first use. Apply water-based lubricant along the shaft, working it into the ribs. Insert the tip with the curve pointing toward the front wall of the body for G-spot or prostate contact. Go slowly so you can feel each rib. At full depth, rock gently to bring the base nub into play. For hands-free use, press the suction cup onto a clean, flat surface. For harness use, fit the base behind the ring first.
Care
- Use water-based lubricant only.
- Wash with warm water and mild soap, paying attention to the ribs, then rinse.
- Spray with a toy cleaner if you wish and pat dry.
- Keep it out of direct sunlight and away from extreme heat.
- Store it apart from other toys so the colors and surface stay clean.

Frequently asked questions
How does the Ribbed differ from the Zigzag and Phallic Rainbow dildos?
All three share the rainbow silicone, suction cup and harness-ready base. The Ribbed is the slimmest at 1.3 inches, has a ribbed shaft and adds a base nub. The Zigzag has alternating bumps and the Phallic is smooth with a realistic head; both are 1.5 inches wide.
Can it be used anally?
The distributor describes prostate stimulation and pegging with it, and it has a wide base that stays outside the body. Use plenty of water-based lubricant, go slowly, and never use any toy anally without a wide base.
Is it firm or soft?
It is made to be soft and flexible, so it bends with your movements instead of holding one rigid line. The ribs are part of the same silicone and compress slightly under pressure.
Will the suction cup hold in the shower?
The distributor says the suction cup is strong and works on any flat surface. Smooth, clean tile or glass gives the firmest hold. Press it down firmly. Silicone itself is unaffected by water.
Why water-based lubricant only?
Silicone lubricant can react with silicone toys and leave the surface tacky. Water-based lubricant avoids that and washes off the ribs easily. The distributor also specifies water-based. Reapply it as often as you need.
