Guest Reviews for Penis-Havers: Fun Factory Manta, Satisfyer Men Vibration, Kink3D X-Lock Cobra

Note from Kate: Here’s some sex toy reviews I asked Matt to write. Enjoy!


One of the benefits of dating (and then marrying) a sex toy reviewer like Kate, is that as her collection grows, so does mine. Sometimes it’s because brands send her toys that are designed for cocks, sometimes I buy them to use with her, and sometimes they’re gifts from my beloved! In this post, I want to highlight 3 toys that I’ve picked up recently that are useful if you’ve got a penis or access to one 😉


The Manta by Fun Factory ($140) is a rechargeable vibrating stroker that’s marketed as “a men’s toy for couples.” Welp, no men to speak of here, but this toy still works plenty well for me and my nonbinary dick.

The Manta has become my go-to vibrator since I purchased it as an upgrade to the Volta, which worked okay but wasn’t shaped quite as well for my particular penis. The Manta fits around the shaft of your dick (3 cm inner diameter), and it works just as well held stationary as it does as a stroker.

It’s a beautiful object and comes in 3 muted colors (I wish the black had been out when I purchased mine). The vibe is cleverly designed with two flexible wings that are ridged for stimulation and to distribute lube as you thrust, though they can take some work to clean.

Some of the most memorable blowjobs of my life have been enhanced by this toy thrumming against the base of my cock while Kate sucked the tip, but you can also use it solo, or to “turn your penis into a vibrator” during penetration. And if you prefer more pinpoint stimulation, you can gently pinch the wing tips around your frenulum for extra intensity.

The handle is looped, so it’s comfy to hold, the motor is powerful and rumbly, the controls are intuitive, the 6 speeds and 6 patterns can always get me off, it’s waterproof, and it’s got a travel lock. You love to see it. This is the perfect toy for someone who’s maybe tried a vibrator designed for clits and liked it, but wants something made with their body (if not gender) in mind.


A very different (but still unnecessarily gendered) take on the penis-vibrator is the Satisfyer Men Vibration ($50), which I won in the Smutathon. Satisfyer claims this enclosed, rechargeable vibrator “feels like a real blowjob,” which it most certainly does not. But that doesn’t mean it’s not pleasurable. The two motors in this toy and the tight black silicone sleeve work together to create powerful suction as the waves of vibration crash over the tip of your penis, occasionally making some hilarious noises in the process.

You can flip between the toy’s 3 speeds and 11 vibration patterns with the “+” and “−” buttons on the body, but as you increase the speed and intensity, you might find yourself wanting to thrust into the sheath as your erection grows. That’ll cause problems if you enjoy deeper stimulation like I do, because this toy only has an insertable length of 7 cm, so you’re limited to vibrating just the first few inches of your penis. Maybe that’s why Satisfyer calls this an “edging tool” rather than an orgasm tool, because that’s definitely what it’s best at.

The inside of the sleeve is wide, so it can easily accommodate a dick whether it’s erect or flaccid, but it also rapidly narrows toward the back to increase the stimulation on the most sensitive spots. With lots of lube, and some experimentation to figure out my preferred patterns, I’ve been able to reliably come with this toy, but the orgasms are never as satisfying as if my whole dick had been stimulated. So I tend to use this vibrator as it was intended: to tease and stimulate the tip of my cock for a while before I’m ready to come in something (or someone) else.

The Satisfyer Men Vibration is a good value if you’re especially into stimulation of the head of your penis, plus it’s waterproof, easy to clean, and carries a 15-year warranty. But if you’re looking for a toy that can quickly and consistently stimulate your entire cock to orgasm, you might not vibe with this one.


Not all the sex toys I own for my penis are about stimulating it; in fact, sometimes they’re about preventing stimulation altogether. Since reviewing the CB-6000 earlier this year, my chastity kink has only gotten bigger, as has my collection of cages. And if you spend even a few hours on chastity twitter, you’ll frequently see the same elegant black cock cage in photos. This cage is the Kink3D X-Lock Cobra ($155–$185), and it was generously sent to me by its maker, who’s an independent creator and active Redditor and Twitter user.

Kink3D cages are individually 3D-printed from hard nylon and nylon composites, so they‘re incredibly strong, light, and smooth. As with all chastity devices, sizing is particularly important, and there’s a detailed sizing guide here. I wear the size S+ cage with a size 2 ring, and it’s the best-fitting and most comfortable cage I own. Because of its open lattice design, it’s easy to wear the X-Lock long-term and maintain hygiene in the shower with just soap and water.

If you’re into tease and denial with your chastity play, the Kink3D cage also makes it easy for your keyholder to see and comment on your locked erections, touch or lick your penis through the cage’s bars, or hold a vibrator against the cage to stimulate you through it, though watch out for potential pinch points which can hurt in a bad way.

I still think the CB-6000 is the best chastity cage for beginners, because tons of sizing options come in a single box. But once you know your sizes and you’re interested in a gorgeous, custom-fit cage you can wear long-term that won’t break the bank, get an X-Lock. It’s been locked on my body for weeks at a time, and I’ve loved every second of it.
