When I first learned the definition of the word "lesbian" I could not, for the life of me, figure out how they had sex without even half a penis between them. After a great deal of thought, I decided that the only sexy bit that protruded from a woman is the breast, and that therefore lesbians must have sex by putting one woman's boob into the other woman's vagina.
