Oral Intercourse

Oral intercourse is here defined as involving sexual contact between the sex organs of one person and the mouth of another.
The sex organs and the mouth are the two most easily stimulated erogenous zones of the body, and it is therefore only natural that they should be brought into direct contact. Indeed, such behavior is quite common in nearly all mammals, and, from a biological standpoint, there is no reason why human beings as the most highly developed and most sensitive mammals should be an exception.
However, in some societies and historical periods, oral intercourse was considered sinful, criminal, or sick, and couples who engaged in it were severely punished. Still, in spite of its traditional religious, legal, and psychiatric condemnation, oral intercourse has always been widely practiced in our culture. This is hardly surprising, since it can be quite satisfying for both men and women. Furthermore, it cannot lead to the conception of a child and therefore naturally recommends itself to couples who worry about unwanted pregnancies and who cannot find the right contraceptives. Unmarried teenagers may also appreciate the advantages of oral intercourse. It not only removes the risk of pregnancy, but also preserves a girl's "virginity". By the same token, boys may enjoy ejaculating into a girl's mouth just as much as into her vagina. In short, many couples discover the various forms of oral intercourse and practice them to their own satisfaction.
