What is the largest thing you were ever able to fit inside your vagina, anus, or penis? For me, I have been anally fisted and I have been sounded by the third size up.
Our largest strapon that my wife uses on me is 8.5 to 9” insertable and 2.2 thick. I think that’s about it. We have a longer thinner one but can’t get it all the way in.
