I wish I had looked closely at the reviews for this product. The hole is quite small so for me it cannot be used, this was apparent right when I opened it. I can fit my index finger in, that's about, much smaller than my erect member.But the larger concern is the quality of the material used to produce this item. I removed the product from the packaging and found a strong odor off-gassing from it and the surface was sticky indicating that it's deteriorating. I washed it twice and it still smells and the surface is still sticky.This product should not be available for purchase on Amazon or any other retailer.
