Yourporn.sexy is about the best there is currently. Not a huge selection, but it's community curated and seems pretty honest relative to the others.  

 
I'm 100% certain that pornhub (and that whole network) is fudging the numbers and showing videos ranked higher than they were organically. This means the content is worse off because it's limited to what the studios want you to see.

 
That said, don't break your dick. http://www.curedeathgrip.com/

Youporn for reasons stated above...

Youporn and Pornhub are my go to's but also like PornMD as a great search engine for free porn.  Often times find more content on a specific porn start or sex act.

There is a  very kinky site called Joy of Spex.

Free Porn

First site I found was Xvideos.com - now use mostly pornhub - thanks for other names as I already waste too much time on porn

I bounce...

back and forth between Tubegalore and porn hub..     Tubegalore is prob the best as it has A-Z categories and has videos from many many porn site...    Its like a porn phone book

In the past I never intentionally went  to Porn sites.
Occasionally I ended  up somewhere I wasn't heading and I visit for awhile.

One day not long ago my PC went haywire, I ended up on chaturbate.    
Now I check, at least  weekly, if any  Gals I know are broadcasting their talents.  
I've seen a few.

I have no clue if chaturbate is considered a big porn site but it certainly has a lot of choices.  

Don't ask me how much for tokens, I've never been the token machine  type guy.
All I know, you can view a variety of sexual escapades without registration or payment.  

chaturbate.com

All live performances. Some are really great.
I have experienced no spam, and it is free, though you get to make requests and get private shows if you tip.
