I get your point and this approach has its benefits as well. Still it was worth a try, it could come up in the next game :-)
If you need some inspiration on bondage items in a game, I can recommend Kinky Dungeon by Ada. Here is a link, it is for free:

But don't spend all day playing this, I am still looking forward to see the next version of EroDungeons.
As additional inspiration for bondage equipment, I will post two links to images that are nice examples for cursed equipment:

To make specific suggestions on items + effect, I need to spend some more time on learning the game mechanics. Before I do that I would like to post one or two more general ideas about game mechanics. But more about that later. Have a nice day and keep up the good work.
