Even though I am small and tight (no children), an average size cock hurts. However, I am a girth queen because I need to be stretched. So, I have avoided 9,10, and 11 inch cocks for the reason....men claim, "I won't hurt you," or "I want to stretch you," -- because I know it's going to hurt.
Some women can accommodate massive girths, I can't. Now, KY is my best friend, but then again, most men enjoy my natural lubrication, friction...the stretching...the widening of my small vagina around their massive girth.
