I would get a yeast infection or bacterial vaginosis from a toy like this. There are so many better toys out there.
You might want to look at some of Fun Factory's good toys. They have the girth you are looking for, and are all 100% silicone, which is body safe and doesn't STINK like PVC often does.
Here's a link to start
some good Fun Factory Toys
The Booster, the Galan, the Patchy Paul, the Stranger II all have good girth, really great vibrations, length, and are 100% body safe silicone! The Astrovibes from Fun Factory don't have as much power, but are good also.
It's a good place to start.
