A prostate massager is a curved sex toy designed to deliver targeted stimulation to the prostate gland — a walnut-sized organ located 5–7 cm inside the rectum on the anterior (front, abdominal-side) wall. A 2016 study published in BJU International found that 71% of men report meaningfully different and often more intense orgasms with prostate stimulation. The category leaders in the UK in 2026 are Nexus (the dedicated brand), b-Swish at the entry-level, and a small set of credible alternatives below.
Why prostate massagers are a separate category from butt plugs
A butt plug delivers the sensation of fullness; a prostate massager delivers targeted contact with a specific gland. The shape difference is the entire reason the category exists:
- Curve. Prostate massagers have a pronounced J-shape so the head sits against the prostate when seated upright. Butt plugs are typically straight or only slightly curved.
- Length. Around 100-120 mm of insertable length — enough to reach the prostate at 5-7 cm depth without overshooting.
- Perineum arm. Many prostate massagers (Nexus, Aneros) have an external arm that presses against the perineum from outside, creating a "double-stimulation" effect that the body responds to involuntarily.
- Motor placement. The motor is positioned to vibrate through the prostate-contact head, not just the body of the toy.
A butt plug can produce some prostate sensation incidentally; a prostate massager is engineered for it specifically.
What to look for
- Body-safe silicone, ABS or stainless steel. Same materials standard as any internal toy — no jelly, no untrusted TPE.
- A large flared retrieval base. Non-negotiable safety feature for any anal toy.
- Pronounced J-curve. The head should clearly angle forward toward where the prostate sits.
- USB rechargeable. Run-time on AAA batteries is too short for the build-up that prostate stimulation requires.
- 5+ vibration patterns. Variable patterns matter more here than for clitoral stimulators because the body's response to prostate stimulation is rhythmic.
- Quiet motor. Most use will be at home where you live with someone; <40 dB matters.

- Empty bowels first. Plain advice. A natural bowel movement an hour before makes everything cleaner; some users douche additionally (use lukewarm water only, never soap or scented products).
- Apply lube generously to both the toy and the entrance. Anal-grade water-based lube is the standard for silicone toys. The rectum does not self-lubricate.
- Insert slowly while relaxed. Lying on your side or back with knees drawn up makes initial insertion easier. The first 30-60 seconds matter most — let the sphincter relax around the toy before any movement.
- Find the angle. Once seated, slight rotation finds the prostate. The sensation is distinct — most users describe it as a deep, warm fullness with a clear "this is the spot" recognition.
- Vibration on lowest setting first. Prostate sensation builds; starting on max overshoots.
- Hands-free orgasm is possible but not guaranteed. Many users report it after 3-5 sessions of practice; many users prefer to combine prostate stimulation with manual penile stimulation. Both are valid; orgasm is not the only outcome worth seeking.
Cleaning + storage
Wash with mild unscented soap and warm water immediately after every use. Silicone, ABS and stainless steel prostate massagers can all be sterilised — silicone by boiling for 3 minutes, the others with 70% isopropyl alcohol. Wash before any other use to prevent cross-contamination from anal flora. Store dry, dark, separately from other silicone toys. Our cleaning guide.

- What is the best prostate massager in the UK in 2026?
- For most UK buyers in 2026: the Nexus G-Rider Plus (~£60) is the best-engineered mid-tier pick — Nexus is the dedicated prostate-massager brand of the segment. The b-Swish bfilled Basic (~£25) is the most-recommended first prostate massager. The Nexus Vibro (~£80) is the premium tier with the strongest motor and full IPX7 waterproofing.
- What is the prostate and where is it?
- The prostate is a walnut-sized gland located roughly 5–7 cm inside the rectum on the anterior (front, abdominal-side) wall. It is densely innervated and is the source of the deep, distinct sensation associated with receptive anal play. Sometimes called the "male G-spot" by analogy with female anatomy.
- How does a prostate massager differ from a butt plug?
- A butt plug delivers the sensation of fullness once inserted. A prostate massager has a pronounced J-curve specifically engineered to make the head contact the prostate at 5-7 cm depth, plus often an external arm that presses against the perineum. The shape difference is the reason it is a separate category.
- Can you have a hands-free orgasm with a prostate massager?
- Yes — many men report hands-free orgasm with a prostate massager, typically after 3-5 sessions of practice. Not all users achieve it, and combining prostate stimulation with manual penile stimulation is equally valid. The 2016 BJU International study found that prostate-stimulated orgasms tend to be slower-building, broader, and longer than penile orgasms.
- What lubricant should I use with a prostate massager?
- Anal-grade water-based or hybrid lubricant for silicone prostate massagers — silicone-based lube bonds with silicone toy surfaces. Anal-grade lubricants are slightly thicker than vaginal-grade and last longer between reapplications, which matters for the longer sessions typical of prostate use.
- How long should you use a prostate massager for?
- Sessions typically run 20-45 minutes, including build-up. There is no upper safety limit for silicone prostate massagers worn comfortably; the practical limit is whenever the experience stops being pleasurable. For first-time use, 20 minutes is a reasonable cap to avoid soreness.
- Are prostate massagers safe?
- Yes — body-safe silicone or ABS prostate massagers with a flared retrieval base are very low-risk for healthy adults. They should not be used during active prostate infection, recent prostate surgery, or any acute haemorrhoid flare-up. Anyone with prostate cancer, BPH or other diagnosed conditions should discuss with a urologist before starting.
