Tube8 is one of the older porn tubes out there. It's part of the pornhub network, so they have the advantage of having access to all the same porn movies that pornhub owns. It's not the best site out there, but it can definitely serve your wanking needs well.
On Tube8 we find that just going to the home page and scrolling down works pretty well. They have daily updates of some really hot mainstream porn videos. Their most popular categories seem to be anal, lesbian, porn stars, and teens. Basically just what you're looking for if you just want to see some hot girls fucking on camera. There's no weird stuff like you'd see on xvideos, where you'll find ugly-looking arab and indian porn, weird japanese fetish shit, amateurs making cheap videos, and more stuff that might kill your boner if you accidentally scroll past it. Nothing like that will happen on tube8, where you can trust that everything you see will be hot as fuck!
One of the best features on tube8 is the channels. All the biggest porn studios have channels on tube8, and most of the channels are frequently updated with the best xxx videos out there. Brazzers, PropertySex, Family Strokes, Public Agent, Fake Taxi, they've got it all. It's awesome because if you're a Fake Taxi fan, you can just go to their channel and find all their HD content right there for your viewing pleasure. It's great!
In the end of the day, there are better sites than tube8. It kind of feels like a worse version of pornhub. The community is smaller, there's fewer videos, there's less amateur content. But for some of you that can be a good thing, as most of the porno videos they have are from professional studios, and organized conveniently by channel. So if you really just want to see hot sexy girls fucking, it can be nice to do away with all the bullshit that you'll find on a site like xvideos. We definitely recommend tube8.
