And given the ease of streaming HD content, and even 4K content with the Roku 4, it shouldn't come as a shock that the porn industry has thrown its weight behind it. As a result, there are numerous streaming-only porn sites that offer full Roku support. However, since they are made with Roku, smartphones, and other streaming devices in mind, you won't be able to download any of these videos like on a computer. Nonetheless, the ease in which they can integrate into your Roku experience makes them winners.

So Who Are the Main Players?

Adult Empire

Perhaps the main player is Adult Empire Unlimited, which prides itself on being the "Netflix of Porn." In fact, it features the most comprehensive collection of streaming porn in existence!

By signing up for Adult Empire's Roku Channel, you'll gain access to unlimited video on-demand content in which you can stream over 38,000 movies and 170,000 scenes, with new content being added on a daily basis. You'll be able to search Adult Empire's porn selection right from your smartphone or tablet, including by scenes, categories, and pornstars.

The video quality of the content offered by AE is also superb. Besides regular 1080p high-definition streaming quality, some videos are even in 4K UHD! They have different subscription tiers, with the cheapest being $12.50 a month if you sign up for a full year. And if you're not sure if you want to subscribe, you can always try its two day trial for just $2.99.

VideoBox

Video Box is arguably the second biggest of the streaming-only premium porn channels offered on Roku. VideoBox, just like Adult Empire, gives you the ability to stream DVD, FHD and 4K UHD porn content and has a library of over 21,000 movies and 118,511 scenes, with more being added all the time.

Another added incentive that Video Box offers is that, if you subscribe for 18 months at $8 a month, they'll even give you a Roku for free! Keep in mind, though, that VideoBox can't yet match Adult Empire in the size of its library and HD offerings as of now.

Subscription Sites

Other stand alone sites also offer Roku streaming channels as a side bonus to keeping your regular monthly membership. There is both similar adult DVD-title based sites at Videos Z and AEBN – both of which have everything from classics to fresh updated licensed videos. Then there is the reality-porn juggernaut, Naughty America, which features all of its fantasy porn sites with support for 1080p and 4K video in one neat channel package.

It's Better Than Traditional Adult Channels and On-Demand Services

There's no denying that watching porn on your Roku device is simply superior to watching it on pay channels and on-demand cable services. By subscribing to one of the Roku porn channels, you'll have unlimited access to a seemingly endless amount of porn titles, much of which is in crystal clear high def and/or 4K resolution.

And, the remote access that Roku offers is enhanced by the ability to control it through your tablet or smartphone, especially with its search feature. Just make sure to subscribe to a premium Adult Roku subscription channel instead of the low budget ones that seem to flood the XXX searches!
