Butt Plug Recommendations?

So this is what I'm thinking guys and girls.. I'm waiting my hubby to do more anal training and develop his hole and stretch out more so I'm looking for any recommendations for some decent butt plugs that he can wear for a few hours at a time. So they need to be comfortable to leave in for a while but still get him opened up more. My aim is to getting into proper fisting/deep anal ultimately so that's kind of why we're wanting to give some a go. Being an anal kinda girl I might even give bigger plugs a try ;)

Thanks
