My girlfriend just saw this thread and made me try it. I can fit in with extra space around my dicklet AND i'm only 3/4 of the way to the end of the tube. Yup, i'm a worthlessly small white boi alright. Already new that but the reaffirmation when she laughed at me after seeing that is so degrading.
I will post my pic shortly, but I have done the test in front of two girls, I don't have the girth to touch the sides, and I get about halfway. I love having a tiny white dick
