Prostate Massager Glossary: Key Terms & Definitions

Understanding prostate play starts with knowing the language. This glossary explains the most common terms you'll come across when exploring prostate massagers, anal wellness, and intimate anatomy — written by experts in sexual health and pleasure science.

Prostate Massage

A therapeutic or pleasure-focused technique that stimulates the prostate gland through the rectum to promote circulation, enhance orgasm intensity, and support prostate health. Learn more in our Complete Guide to Prostate Massagers.

Prostate Gland

A walnut-sized organ located just below the bladder in men and people with penises. It produces seminal fluid and responds strongly to gentle pressure or vibration — often called the “male G-spot.”

P-Spot

Short for “prostate spot,” this term refers to the prostate gland as an erogenous zone. P-spot stimulation can create deep, full-body orgasms distinct from traditional penile stimulation.

Perineum

The sensitive area between the anus and genitals. Many prostate massagers, such as the We-Vibe Vector+, include external vibration against the perineum for dual stimulation.

Dual Stimulation

The simultaneous stimulation of two pleasure zones — typically the prostate (internally) and the perineum (externally) — for more intense, layered sensations.

Anal Sphincter

A circular muscle that controls the opening of the anus. Relaxing this muscle is essential for comfortable, safe insertion of prostate toys. Controlled breathing and water-based lube help ease the process.

Flared Base

A widened safety base at the end of anal and prostate toys that prevents over-insertion. Always choose toys with a flared base, such as the b-Vibe 360 Plug.

Bi-Rotational

Refers to prostate toys that rotate in two alternating directions for dynamic, massage-like stimulation. Found in advanced devices like the Nexus Revo Extreme.

Rechargeable

Modern prostate toys use USB or magnetic charging instead of disposable batteries. Rechargeable designs are more eco-friendly, consistent, and discreet.

Waterproof

Indicates that a toy can safely be used in the bath or shower. Look for an IPX7 rating or higher for full submersion. Always ensure charging ports are sealed before cleaning.

Body-Safe Silicone

A medical-grade, hypoallergenic material used in high-quality sex toys. Non-porous and easy to clean, it’s ideal for hygienic prostate play.

Water-Based Lubricant

The safest and most compatible lubricant type for silicone toys. It provides smooth glide without degrading materials. Avoid silicone-based lubes, which can cause surface damage.

E-Stim

Short for “electro-stimulation,” a technique that uses mild electrical pulses to stimulate nerves and muscles for unique sensations. Featured in toys like the Mystim Electric Eric.

Perineum Stimulator

The external arm or pad on a prostate massager that vibrates or pulses against the perineum while the internal shaft massages the prostate.

Pelvic Floor Muscles

A group of muscles supporting the bladder and sexual organs. Strengthening them through regular prostate massage or kegel exercises improves orgasm control and erection quality.

Insertable Length

The portion of a toy designed for internal use. It’s measured from the tip to the point where the flared base or handle begins. Always insert slowly and comfortably within your limits.

Beginner Prostate Toy

A smaller, smoother toy ideal for users new to prostate play. Start with gentle designs like the We-Vibe Vector+ before progressing to larger or rotating models.

Advanced Prostate Toy

Larger or feature-rich toys (e.g. rotating, vibrating, remote-controlled) intended for experienced users seeking deeper stimulation and stronger sensations.

Remote Control

Wireless functionality that allows solo users or partners to adjust vibration or rotation settings from a distance — perfect for discreet or shared play.

Prostate Health

Regular, safe prostate massage may support circulation, help relieve tension, and improve sexual wellness. Always use clean, body-safe toys and proper lubrication.
