The G-spot, which is more acccesible through the anus, is one of the most sensitive arrousal points of the human body. Many people can orgasm just from the stimulation of the G-spot. Sexual stimulation in this manner is totally different from a rectal exam. A rectal exam is uncomfortable for many reasons, mainly because people are usually tense because they are not happy about being examined, and their anus is not used to being stretched. Similarly, most women do not enjoy their gynecological exam because it is an exam and not a sexual situation. They usually don’t enjoy intercourse the first time they have sex, either, because the vagina is not used to being stretched.
