I am around 5" and have used them before. Had one that went over mine and was 9". I loved the experience, mainly her reaction. We had a few drinks beforehand, which helped. She said she was looking at me and got confused, as she was getting fucked by a big dick, and it was me. She was so used to by small dick. Again the drinks helped her feel like she was getting fucked by huge dick. It took time for me to adjust. I didn't know how to fuck with that long of a cock. Was of course used to short stroke of just a few inches to keep my 5" from falling out. I could now stroke with deep 7" strokes. I am sure it wasn't a great fuck for her, cuz I would catch myself doing tiny strokes again. But to see her face and moans when I went past my normal limit of 5", told me I was always barely fucking her, giving her the full 9", felt like I was finally fully fucking her. I got to feel like a big dick stud for awhile. I loved it
