Aneros MGX Syn Trident Prostate Massager

The Aneros MGX Syn Trident is a hands-free prostate massager from Aneros' Trident series, with a soft silicone coating over a balanced, slim body. It has 3.5 inches of insertable length, a moderately focused head and a ribbed stem, and it's shaped to move on its own as you tense and relax your muscles. Aneros says it suits every experience level, and the coating makes it a gentler-feeling option than the brand's hard-surfaced models.

How a hands-free prostate massager works

Aneros massagers don't vibrate. Instead, once the toy is in place, light contractions of the muscles around your anus cause it to rock against the prostate, while the external arm presses on the perineum. You control the movement entirely with your body, so it tends to build slowly, and most people need a few relaxed sessions before they get the hang of it. Breathing slowly and keeping contractions gentle works far better than squeezing hard.

What makes the MGX Syn different

Aneros describes the stimulation as moderately focused: the head is shaped to press on a defined area rather than spreading pressure widely. The stem is ribbed, which adds extra sensation at the entrance with each movement. Like the rest of the Trident series, it's designed to contact several areas at once, which Aneros lists as four zones in total. And because the body is balanced, small contractions produce noticeable movement. The silicone coating gives the surface a softer, velvety feel than plain hard plastic.

Size and fit

The head is 0.80 in wide and the mid-ridge 0.87 in wide, so this is a slim toy; if you've used fingers or a small plug, it won't feel large. The listed stem-to-perineum distance is 1.5 in, the gap between the insertable part and the external arm. If you'd like something with a different shape in the same family, compare the MGX Trident or the Eupho Syn Trident.

Your first session

Empty your bowels first and take a warm shower to relax. Lie on your side with your knees drawn up, or on your back. Use a generous amount of water-based lube on the toy and yourself, then insert it slowly, letting the curve follow your body until the external arm rests on the perineum. Lie still for a few minutes and get used to the feeling before you try any contractions. Expect the first few sessions to feel subtle; that's normal.

Positions to try

Lying on your side with your top knee pulled up is the classic starting position, because it relaxes the pelvic floor and keeps pressure off the external arm. Once you're used to it, try lying on your back with knees bent and feet flat, or face down with a pillow under your hips. Sitting puts pressure on the arm, so save it for later. Change position if the sensation fades; a small shift often brings it back.

Lube and care

Stick to water-based lube with a silicone-coated toy; silicone lube can damage silicone surfaces. Wash it with warm water and mild soap or a toy cleaner after every use, rinse well and let it dry before storing it in a pouch.
