If so how did you find it ? Read the reviews but not able to get any girth comparisons to see if it would be suitable for my Girth, 5 inches lots of people saying they were not confident using for VP and a few saying it simply slipped off.

i have looked at the details and converted the size to circumference and get 3.9 inches but would love to get some feedback from anyone close to my size.

Really like the look and thought of this to go with my Dominix doughnut Which by the way is absolutely awesome.
