I've never used a metal cock ring for fear of it getting stuck, though many people use them around their cock & balls. I prefer cock straps, or ones with a magnetic release.
I find that some of the leather ones available commercially, to be too tight to wear for any length of time. I go for the fully adjustable ones, or even homemade.
I'm past middle age now, so don't stand up at the angle I used to, however a cock strap is a great help & certainly brings back those 'Youthful days'.
I would certainly recommend trying one for that turbo charged feeling. Go for the type that goes around the cock & balls, just nicely snug will do at first.
