This porcelain cockring will not only decorate your dick but help it stay hard. Wearing it can enhance sensations so it’s fun to use for soloplay and intercourse. It’s design is rounded off and won’t hinder penetration. The shape is complicated to explain but it follows the body. Round at one end, slightly oval at the other, the tube is concave a little and the wavy shape seen from the side follows the shape of the body.
Since the material is rigid I can safely recommend about 1 to 2 cm restriction. Finding the size you need means measuring the circumference of the base of your erect penis minus how much tighter you want it to be. Everyone has a different preference when it comes to tightness, if you have previous experience with rigid cockrings I would recommend measuring to see what’s your favorite size.
For example; if your penis measures 13cm circumference in erect state I can recommend getting the 11 or 12cm cockring, depending on how much restriction you prefer.
The ring should be tight enough to be effective, but never so tight that it causes pain or restricts blood flow. If at any point while wearing it starts to feel uncomfortable or hurt I’d recommend taking it off. Sliding it off should not be a problem but I can recommend using some lube.
