Occasionally one finds women who greatly prefer anal intercourse to any other kind of sex play. Such was the case with Linda G-, who wrote, “Anal intercourse is, for me, a far more satisfactory means of obtaining multiple orgasms than vaginal intercourse and I have been enjoying the former act for nearly fifteen years, averaging no less than three times weekly. There have been no signs of hemorrhoids, no irregularity, and since the first few times I experienced no pain. There is considerable pleasure for me during the act, and after the emission of semen I enjoy a five or ten minute period of utter serenity.” (Schoenfeld, Dear Dr. Hip Pocrates,) In exceptional cases, anal intercourse may be combined with more orthodox forms of sexual activity, as the following letter indicates: “Recently my husband and I have submitted to “double-screwing,” i.e., one penis in my vagina and a second in my rectum simultaneously. It isn’t easy to do, but when it is I am transported into another world! For me to reach climax half a dozen times is not unusual and each orgasm is more gratifying than the one preceding it.” (Quoted in ibid., pp. 7-8.) In these cases, one feels sure, at least part of the pleasure reported stems from the fact that the subject is participating in a “forbidden act,” violating a deeply held social taboo. There are very few women in whom the vagina and the adjacent organs, together with the nerve endings which provide the physical stimulation needed for sexual arousal, are atrophied or dysfunctional. That is, there is seldom any clear physiological reason why the anus should be preferred to the vagina as a receptacle for the penis. The preference is far more likely to be due to psychological peculiarities of the particular individual.

In virtually every case history that we can find, the subject reports that first attempts at performing anal sexual intercourse were accompanied with at least a moderate amount of pain. Whether the individual was male or female, they found that a penis could not be inserted into the rectum with ease.
