It fits my partner perfectly. It’s the perfect size , this is our first time experimenting with urethral play , the size is perfect for beginners to intermediate at least . Make sure you use a sterilized lube that’s made to go inside of the body before any urethral play . This was definitely a fun new thing to try , we tried this along with butt play and he definitely enjoyed himself . It was easy to use and very easy to clean and sanitize afterwards ! Beginners should absolutely take their time and make sure your partner is comfortable the whole time
