I don't think there's any correllation between a woman's body size and the dimensions of her vag. And vagina size doesn't seem to have much correllation with her ability to "take it", I've had some that seemed comparatively "loose" who said I hurt them, and some who seemed almost painfully tight to me who just couldn't get enough. It seems to be mostly a mental game, and how much they can relax it. Attitude and aptitude help; if they seem afraid of it at first glance, things are not going to go well, but if they can't wait to try it on for size, then it's gonna be fun for everyone. Experience is a big factor too, even if we have a bad first experience but I'm lucky enough to get a second chance to try again, in time she can learn to accommodate and enjoy.
