Tie wraps,the reusable kind,are OK, but make sure that you have some wire cutters handy!
Metal cock rings are best,about 45 mm diameter, and they go around your balls and cock.
I’ve found curtain rail sliders great I do have a big steel heavy one on that looks cool but for me silicone ring around my balls and a curtain ring around my cock
I got some silicones from LH and tbh I'm not that impressed. Haven't tried them properly yet though. They give three rings in one pack, the third of which is too big to be off any use for my small wiener. I will try them someday, see what staying power they provide.
