Not to get all ethical about porn, but unless you’re viewing content from verified accounts, pornhub and xhamster are trash imho.
Only fans and manyvids have some amazing content and a lot of creators on there have a free to access profile so you get an idea of what they’re about and will often run discounted subs. Some of the best porn I’ve ever seen is on only fans to be honest, well worth paying for.

Not sure it’s one for you and your hubby though , it might put both your ‘jaws on the floor’ 
Porn hub or youporn
XNXX is quite good. My OH uses pornhub when we watch it together. @Sophie01 I’ll give vixens a look I think 
WOW! That’s a jaw dropper to be sure. Very intriguing 
My wife and I like making our own at home. More safer and turns us both on.
Now there’s an idea!! 
Various sub-reddits are great especially for finding real amature. I like r/gonewildaudio and r/realgirls but there’s plenty out there for all interests. I also recently found Bellesa, haven’t had a chance to properly dig in but so far so good.
Literotica has some great written and audio material if you’re willing to look (and listen!).
For a couple watching porn we like Bellesa it seems to be more focused on pleasure for ladies.

I prefer the amateur/homemade videos. Why not make your own to watch? I get massively turned on by making and watching my own videos 
Pornhub then SinfulXXX is quite classy, believe it or not. Great looking actors, ample ‘assets’ and well shot eroticism…enjoy x
You can’t beat making a home made amateur wank video and sending it to your partner to view later,or at for their pleasure
Porn Hub
Xhamster
Bellesa, recently launched a plus option, marketed as Netflix of Porn. Have switched from Pornhubpremium.
Xvideos usually, I prefer to find amateur accounts rather than watching proper pornstar videos.
Porn Hub is my #1 .
