This is the most comfortable strap on that I have ever tried. The straps sit on my hips very nicely and they don't get in the way when I am using it. It took a little while to figure out how to put it on, but it was worth the trouble. The dildo was secure in the harness and did not budge when I used it. I used the dildo for anal. It is smooth thin and short, so it is perfect for that. It probably could work for vaginal but it seems kind of small. Maybe it would be perfect for a beginner or something, but my girl likes it anally.
