I use anal hooks as part of bondassage play.

And I have to tell you that although some men love it, some ... well, it takes knowing how to use that hook and then angle and sometimes, it can be a bit much for the average guy who is used to anal play.
I've also used the top picture, the dildo with the smaller to larger balls ... but in glass play. I like the handle a lot.
Again, men love it if they're alright with the harshness of the material.
I love this topic, Dallas. I need to add to my collection. The double dildo one looks interesting!!!
Guess it's all in the angles. lol
