A beautiful, voluptuous woman goes to a gynecologist. The doctor takes one look at the woman and all his years of professionalism is thrown out the window. He instructs the patient to undress. Once she has disrobed, the doctor begins to stroke her thigh and asks, "Do you know what I'm doing?" "Sure," she says, "you're checking for any abrasions or dermatological abnormalities."
"That's right," says the doctor. He then fondles her breasts. "Do you know what I'm doing now?" he asks. "Sure," says the woman, "you're checking for any lumps or breast cancer." "That's right," replies the doctor. He then removes his pants and proceeds to enter the woman from behind.
"Do you know what I'm doing now?" he asks. "Yes," she says, "you're getting herpes."
