Looking for a chastity device that works well with the foreskin

So far, the CB-X Curve appears to be the right size and shape, offering good breathability with easy access for cleaning underneath. I also appreciate that the lock folds down; I prefer not having a large lock bulging out on top. However, the rings seem quite chunky, which reduces discretion somewhat. Haven’t discovered any suitable alternatives yet though. It would be helpful to hear reviews from other uncut guys who have used the Curve.
