To accomplish heterosexual sexual intercourse, a man's penis must be erect or hard enough to push through or penetrate the resistance offered by vaginal tissue. The natural lubrication afforded by the vagina aids penetration by making passage through the vagina easier. Penile penetration of the vagina often results in male orgasm, and the ejaculation of semen and may, by itself, also provoke female orgasm. Orgasm solely by penile penetration does not happen as often for females as for males. Because most of the nerves that stimulate female sexual response are located in the outer third of the vagina, deep penetration is not necessary for female sexual pleasure, although some women enjoy the sensations of deep penetration. Penetration may also stimulate the woman's G-spot, a region of the anterior vagina wall that arouses surrounding tissue.
The penis may also penetrate parts of the body other than the vagina. Penetrating the mouth as in fellatio or the anus as in anal intercourse (also known as sodomy) were traditionally understood as unnatural in the logic that defined penetration as occurring only in a vagina. Such penetration can occur between males and females as well as between males and males and males and members of other species. Although such penetrations have long been a part of human sexual practice, they were repressed and gradually criminalized after the rise of Christianity. In 2003 a Texas law criminalizing sodomy and oral sex was deemed unconstitutional by the Supreme Court in Lawrence v. Texas. In the United States most sexual practices involving consenting adults are no longer criminalized.
PENETRATIONS WITHOUT PENISES
Most notions of penetration are phallocentric or focused on the penis as a necessary element. Sexual penetrations, however, also occur with objects other than a penis. Dildos, which have existed since prehistory, are objects designed to penetrate both the vagina and the anus. Dildos, which often look like penises or have a long, cylindrical shape, are used by both females and males. Some lesbians use dildos, which strap on to one participant's body. Some dildos include an attachment to stimulate the G-spot. Others have two heads and are used for simultaneous penetration by two women. Smaller dildos, called butt plugs, are designed to penetrate the anus. People have also used other objects ranging from cucumbers and carrots to light bulbs as instruments for penetration, although some of these objects can cause injury.
