Well, as you know the vagina is elastic, so it's not like there's a wall and once you get there it's over. In general I feel "bottomed out" with about 7 inches. After that I get a stretching feeling because my pussy is trying to accomodate a larger size. A little stretching is a very nice, full feeling, and I love a cock in the 7-8 in. range :tongue: , but much longer than 8 in. starts to get uncomforable.

And yes, girth plays a part in the overall feeling of fullness. I don't know exactly what would be "too thick" for me. I like good thickness but I'm sure there'd be a limit. I hope that answers your question.:wink:
