"Long John" is one of our recommended urethral catheters, made of 100% body-safe material. Ideally, you put some lube on it and stick it in your penis. Should you feel the urge - or pleasure! - to piss, feel free to do so! Thanks to the hollow catheter and the two holes, every liquid can freely flow through it. The metal ring makes sure you don't insert it too deep or that it gets lost inside of your body.
