Designed specifically for men, the SpareParts Deuce Male Strap-On Harness Magnum is a harness that allows for double penetration. Whether it’s with a biological penis alongside a dildo or just two didos, this harness includes two holes – unlike the standard harness that just includes a single one. Featuring a 4-strap design that allows the harness to fit like a jock-strap harness, the Magnum size features larger penis holes for those who want to use larger dildos or have a thicker biological penis. This harness is also available in Size A or Size B for different body sizes. The under-the-butt straps adjust via buckles while the waist straps adjust through a Velcro system and buckles for minute adjustments.
The packaging for this harness is fantastic in terms of presentation as well everything it includes. You have instructions about how to use it, and the inside is even wrapped in nice tissue paper for a luxurious touch. The harness comes packaged in a simple, zipper-shut bag; it fits back into this bag for really easy storage. The box is fantastic for gift-giving, and if you choose not to use the zipper bag (I’m not sure why you wouldn’t), the bag can work for storage as well
Like all Spareparts harnesses, this harness is extremely comfortable. It was really designed for comfort, even. Many harnesses are designed more for short-term use, so while they’ll be tolerable for comfort in a short bedroom session, they won’t be comfortable for long-term wear. The Spareparts Deuce harness is comfortable for both short-term and long-term wear. The spandex material means that it stretches out where you need it to while also being breathable and really comfortable.
One of the biggest concerns about a strap-on harness for guys is whether it will have the needed extra room for testicles. This was specifically built to provide the room you need, and it does a good job of it. If anything, it might have almost “too” much room from our testing. However, this extra room means that it’s comfortable to keep the penis inside of the harness when it’s flaccid instead of sliding it outside of the harness. It gives you options for whatever makes you most comfortable.
During use, everything lines up really well. There will probably be a slight “off-set” depending upon your anatomy since not everyone is built in the exact same way, but from our experiences, the off-set is so small that it’s barely noticeable. The harness is extremely comfortablet to wear, and nothing is “pulling” awkwardly.
On the other end of that, once in place, the two penises line up relatively well. You might have to do some minor adjustments, but it’s easily do-able to enjoy double penetration while wearing this harness. It took some work on the angles to get both at the same type and depth of penetration, but once you get used to dealing with a second phallus, the harness does a fantastic job of making it possible to enjoy both at once.
I love that it includes a flexible penis hole. If you’re hard or want to, you can slide your penis through the included hole to include your penis in the fun. If you aren’t hard, you can still use the hole if you want, but the penis can also be kept inside the harness instead of through the hole instead. There’s enough room in the “pouch” to have the flaccid penis resting inside of the harness instead of pushing it through the included penis hole if you want. It’s up to you.
This is a size Magnum because it’s designed to have a larger-than-average biological penis hole. For those that find many condom brands are uncomfortably tight, the Magnum size might be a much better choice for you. Length doesn’t really make a difference, but it’s more about the girth of the penis around the base. So if standard condoms don’t really bother you, definitely go with the standard-sized Deuce harness, but if you find that standard condoms feel too tight around the base, the Magnum Deuce is better for you.
When it comes to the O-rings for both the penis and the dildo, they are built-in. You can’t exchange them for other sizes. However, the O-rings are relatively flexible and stretchy. This means it’ll stretch out to fit a dildo much larger than it seems, and when stretched out, it actually does quite a better job of holding the dildo “in place” as well.
To clean this male strap-on harness, you’ll want to use warm water and anti-bacterial soap. To make it even easier, though, if you want, this harness is machine-washable and can be washed in your dryer. It shouldn’t be put into the dryer, though (I’ve been known to accidentally put mine in the dryer, though, and it survives fine). For simple storage, it fits really easily right back into the drawstring bag. To keep your harness looking nice, it seems to work best to wash it right after use to get any fluids or lubricant off of it. Again, always allow the harness to air dry for best care.
Overall, the SpareParts Deuce Magnum harness makes it really easy to explore double-penetration without having to bring another person into the bedroom. The Magnum size is much more comfortable for those with a thicker penis while the harness fits really comfortably on the body as well. The velcro adjustable waist straps make it easy to adjust on-the-go, so there’s no more fiddling with buckles when you just want to play with the action. The Deuce is designed well with multiple options for how the guy wants to use his biological penis – including the option to just use two dildos instead of a biological one. If you want to try double-penetration, this is honestly one of the best harnesses you could buy. Thanks to Dallas Novelty for providing this male strap-on harness for my SpareParts Deuce Magnum review.
