The Tantus Ryder is fantastic and routinely gets some of the best reviews of any plug ever. I will note, however, that it’s not exactly easy to insert, because it doesn’t have a very tapered tip. But if you’ve got some practice, it’s not too bad. And suuuuper comfortable once inserted.
The Fun Factory Boosty is also a great one.
If you’ve got money to burn, the large Njoy Pure Plug should be on your list of plugs to consider. It’s called the large but it’s not really that large (1 1/2” in diameter, same as the other two I mentioned), and like all the other Njoy products, it is flawless. Truly one of the best best best anal toys ever invented.
