Deepthroating Dildos and Dongs

My favorite is my 8.5" Mr. Limpy. I can take the whole thing easily. I just wish that made a longer one. Once I get it about 8 inches in I can feel it push through a sphincter in my throat. After doing this for a while, my face is coated with saliva and I love it. It really makes the precut flow after all of the excitement. I've tried a few of those jelly dongs but the taste is unbearable and not so kind to the throat. I am interested to know your experiences and recommendations on something to take me to the next level in deep throat practice.
