The nJoy Pfun Plug is a ~$90–$120 solid stainless-steel anal plug designed specifically to target the prostate — nJoy's answer to the question "what if a butt plug could actually hit the p-spot?" It's part of nJoy's legendary stainless-steel lineup (which also includes the Pure Wand and nJoy Eleven, both long-time reviewer favorites already in our guide). The Pfun trades the Pure Wand's universal G-spot/P-spot curve for an anatomically specific bulge-and-stem shape optimized for prostate contact.

Why It Matters

The Pfun is part of a small but growing category of high-end, non-motorized metal sex toys that prioritize material quality and lifetime durability over features. For gender-neutral anal play specifically, the stainless-steel options from nJoy, Fun Factory, and Tantus have become reviewer defaults because they bypass the material controversy (medical-grade silicone vs. TPE vs. ABS) and simply can't degrade. At $90–$120 it's an investment, but it's also an investment you make once.

Specs: 3.5-inch insertable length, 1.25-inch max diameter at the bulb, 11-ounce (310g) weight, cast and hand-polished 316 stainless steel. The T-bar base is wider than competing metal plugs and frequently cited in reviews as unusually comfortable for a steel plug — comfortable enough to wear seated for extended sessions. No motors, no batteries, no app, no electronics. The plug's weight and rigid steel construction do the work: the prostate receives firm, fixed pressure from the bulb while the user's own movement (muscle contraction, breathing, slight rocking) generates sensation.

Reviews from ToyfulReview, Kelvin Sparks, and retail-page reviewers converge on two points. First: the Pfun delivers prostate stimulation intensity that vibration-based plugs can't match — the rigid steel transmits every muscular contraction directly to the p-spot, creating a fullness sensation that's distinctly different from silicone or TPE plugs. Second: retention while walking is weak. The shape is designed for stationary use (sitting, lying down, partnered penetrative sex with plug in) rather than public wear or extended walking. Users who want a plug they can wear grocery shopping should look at the b-Vibe Novice or Snug Plug 2 (already in our guide). Users who want maximum prostate intensity at home should try the Pfun.

Price and availability: $90–$120 direct from nJoy.com, also widely stocked at SheVibe, Babeland, Good Vibrations, Shopabunda (with BNPL financing at $18/month), and Amazon. Lifetime durability — the stainless steel doesn't wear out, crack, or degrade. Most users will own this once and never replace it. Ships in a simple velvet pouch.

Materials: 316-grade stainless steel, medical-grade, non-porous, completely phthalate-free. Boilable for sterilization, dishwasher-safe top rack, bleachable, compatible with any lube including silicone and oil-based (where most silicone toys are not silicone-lube compatible). Temperature play capable — runs under warm or cool water before use to transmit temperature.

The bottom line: buy the Pfun if prostate stimulation is the priority and you want the most direct, rigid, intense approach available at this size. It's the advanced user's choice for seated or supine play, for temperature play, and for anyone who's outgrown silicone plugs and wants something with no motor, no battery, and indestructible construction. Gender-neutral — the shape targets the prostate but works for any body seeking firm anal fullness with a weighted, rigid toy. Skip it if you want to wear a plug all day (look at b-Vibe Snug Plug 2, also weighted but silicone with better retention) or if you need vibration (Lovense Edge 2 or LELO Hugo 2 are our app-controlled picks).
