Cockrings that are made for you, with the exact size for your cock.
Typically, an adjustable cockring is going to be made out of rubber or silicone, which is what gives them their stretch. Another option, if adjustable-ness is your priority, is to go with a kit that contains different size cock rings, so you can choose one that feels best for you. And while cock rings should be snug, they should never be painful. The second they feel like they're starting to cut off circulation, you should remove them. Rings that are too tight can cause a ton of complications, so the best thing to do choose a variety pick so you can find your ideal size before committing to one individual toy.
