Just for the final answer, for most women, the average American male size is adequate to stimulate them to the point of orgasm, some women prefer wider, some women prefer longer, some prefer both, most women are fine with the average male size (about 6" long, and about an inch and a half thick, about the perfect size for your standard condom).
