Women are human beings also, meaning that when they are sexually excited they want to be penetrated by a penis, preferably a rather large one...

*snerks at the sheer stupidity of that statement*

Except for all the lesbians; who when they are sexually excited (and at any other time) do not want to be penetrated by a penis of any size...

...oh, and all of the women who prefer non-penetrative sex.

...oh, and all of the women who care more about the personality of the person they are sleeping with than the dimensions of that person's genitals.
