Rockarmy Sherman realistic dildo with density

This time, you’ll choose this dildo if you’re looking for a realistic sensation with a firm core and a softer exterior. The Sherman uses contrasting densities to provide gradual penetration suited to different intimate areas. I’d place it in the entry- to mid-range category for anyone who wants realism without complications.

Dual-density TPE and care

The Sherman is made of dual-density TPE (thermoplastic elastomer). This design combines a firm core that provides stability with a softer outer layer. The material quickly reaches body temperature, improving comfort from the very first use. The surface’s silky matte finish provides a pleasant, non-sticky tactile sensation.

I find that dual-density TPE creates an interesting balance between firmness and flexibility. Care is simple: mild soap and lukewarm water are enough after each use. You can also use a specialized cleaner such as Waterfeel Toycleaner for thorough hygiene. Dry it well before storing. The material is IPX7 waterproof, so you can rinse it under water without worry, but avoid prolonged immersion.

Dimensions, size and hands-free use

The Sherman measures 24 cm in total length and 4.62 cm in diameter. The wide suction-cup base (approximately 5 cm in diameter) is designed to adhere to any smooth, flat surface: tile, glass, varnished wood or a bathtub wall. This allows for completely hands-free use by positioning the accessory on a stable surface at a comfortable height. Its 442 g weight gives it good stability without making it too heavy.

These dimensions place it in the standard category: neither compact nor enormous. It’s a versatile size suited to most body types, including for a first experience with a realistic dildo. The wide base also ensures safer anal use by limiting the risk of overly deep penetration.

Compatibility and ways to use it

The Sherman is compatible with:

• Pegging harnesses (strap-ons) — the base fits standard O-rings
• Water-based lubricants only (TPE is sensitive to oils)
• Solo or partnered use
• Showers and bathtubs (IPX7 waterproofing confirmed)
• Mild sex-toy cleaners or unscented soap

I recommend always using a water-based lubricant to maximize comfort and reduce material wear. If the toy is shared, a condom is strongly recommended because TPE is porous. Between us, it’s good hygiene practice even in a monogamous relationship.

Who it’s for and who it isn’t

Who it’s for: People who are new to realistic dildos and want a balanced sensation. Those who enjoy hands-free use thanks to the suction-cup base. Couples who practice pegging. Anyone who tolerates TPE well and wants good value for money.

Who it isn’t for: If you prefer the extreme firmness of medical-grade silicone or glass. If you have significant skin sensitivities to TPE (test it on a small area first). If you’re looking for an ultra-discreet dildo for travel — at 442 g and 24 cm, it’s not particularly discreet. I’d point you instead toward our more compact silicone dildos or a smaller model from the same brand.

Friendly advice — The Sherman works best with a good lubricant and a first session without pressure. The dual-density construction makes all the difference once you find the right angle.
