The inner diameter is pretty big. I think I'm about average size down there and it was way too roomy. The strap was also too big. I think that if you fit this device you are probably already XL.
The pictures don’t do this thing justice. It’s really girthy and a good shape. Very realistic as far as design goes but it is big. XL is very accurate for it so just be prepared. It fits well however the ball strap is very small but it does stretch a bit. Will require some time for the partner to warm up to. But overall satisfaction is a bi product of this. We are very pleased with the purchase.
Prompt delivery. Bigger and better than expected
Just like the title says. At first she was a little set off about it. But loves it now
