This is awesome! I haven't tried urethral sounds yet but the feeling I get from this tells me I'll have to get some. This gives you unbelievable sensations as it slides in and out of your cock. I am working out some issues with the size of the ring as both options are too small for my head to work through. So, extended wear hasn't been an option for me yet. But, I'll get it figured out and I'll be on my way to wearing this for a couple days at a time. By far the best cock toy I've purchased to date.
