I've been with two 4'10" women in my life. One could take me with ease, the other we had to call it off after a few strokes as it was too painful for her. The one who could take all, and another woman I've been with who is 5'0" both drove me to a quick shot every single time. Both had long legs and short torso. I'm thinking it had something to do with the angle of their vaginas, as I distinctly remember a lot more pressure/friction than normal on the top of my glans. This hasn't been a problem with any of the women I've been with before, in between or since.
At 6'4" though, women under 5'5"ish just don't do it for me anymore. To awkward to make out while standing, and as mentioned above, some of my favorite positions are a little awkward as well with women of that stature.
