The tallest woman I've ever been with was 5'10". She loved big 'uns. In fact, she left me to go back to her ex, whom she said was "a lot longer" than I am. I did bottom outin her, so what she's doing with the extra length, I don't know.
My ex-wife is 5'4" and can take me with room to spare, certainly more easily than the taller woman could. I can't remember bottoming out in her. I've had sex with a couple of smaller ladies, in the 5' - 5'3" range, and they were all different in terms of their ability to accomodate me. Not that I've had that much experience, but I would say there's no correlation etween height and vaginal depth.
This is about the 6th time I've answered this question in one form or another.
It would be nice if some of the taller ladies from this forum would give their perspective. IIRC, there are some of them around here.
