There have been a few threads on this.but I’d like to make a point..
I believe the best selling woman’s vibrator in the world is the Rampant Rabbit.according to the ann summers’ website:
8” length with 5¼” girth
Now, every other vibrator on there is shorter in length.they used to sell some monster but they’ve stopped selling it? (I can only speculate due to lack of interest)
Plus, you must consider that the rabbit head is an inch up the shaft, so they’d only use a max of 7”.
I presume Ann Summers have a better idea (market research) and the women that buy it, than we do?
