When I first seen this toy "The Yooo", I started thinking that some of the ladies might want to insert the whole Yooo? If so I'm quite curious if it is a good toy for this purpose, and if it makes for a good "O" for you?
Have you tried reading all of the reviews to see if anyone has used it that way? Please read reviews before taking your questions to the forums, provided that you did not find your answer.
That being said, that's not really what this toy is meant for and I'm pretty sure it's not even possible or at the very least difficult. This toy is mostly meant for massaging and also clitoral/labial stimulation.
