It's so and so
The Goku-IBO Virgin was a tight fit due to the internal texture. The internal texture have tiny nubs. I felt like the tiny nubs were too firm. I wish the tiny nubs were softer and further apart to give space for exploration. The tiny nubs does give a tight sensation (only 1 type of stimulus feeling). I am not a fan of tight sensation because it doesn't allow space to breathe and it didn't feel comfortable for me. The clean up is a bit harder to clean because it's a narrow tunnel. I also notice while cleaning it, when you reach at the end of the tunnel, there's a pointer nub and you can definitely feel it. Unfortunately, I was not able to experience that feature since it was too much of a uncomfortable tight fit for me. If you enjoy tight sensation then it's the right toy for you.
