The average vagina is only 3 or 4 inches deep and the majority of the nerves are concentrated in the first, or outer, third of it.
Sure vaginas are very stretchy and can accommodate much more than 3 or 4 inches but even that much isn't really necessary because the nerves are in the first 1 to 1.5 inches.
Hope that helps you to be more confident.
