I've always been told that my eyes are bigger than my, uh...mouth.
That said, I know at this moment in time, I'm not going to be able to accept a larger cock, as much as I'd like to think I can.
That said, for now, I'd much prefer a smaller cock. That said, I know I'll enjoy licking it like a lollipop, kissing it, and getting as much of it in my mouth than I could with a larger one.
