This toy allowed my full member to fit inside while erect and is shaped in such a way so that it didn’t create a bulge where the end of my penis was located. The shape while filled with my erect penis was slightly larger in diameter but still looks natural. The increase in diameter with this on is not as much as some other toys. My wife enjoyed the extra size without having a painful experience. You will need to communicate with your partner to ensure that you are not getting too deep if they are not used to having large toys inside of them.
