anal masturbation
Anal masturbation is manual erotic stimulation focusing on the anus and rectum. For humans, common methods of anal masturbation include manual stimulation of the anal opening and the insertion of an object or objects such as fingers, feet, fists, phallic shaped items, water play, or sex toys such as anal beads, butt plugs, dildos, vibrators or specially designed prostate massagers.
==Method==
The most common explanation of how stimulation can be derived from anal masturbation is that the rectal opening contains many sensitive nerve endings. Other explanations include the potential for myofascial release of various pelvic floor muscles that hold significant tension for certain individuals. Orgasmic function for a male depends in part on healthy functioning of the smooth muscles surrounding the prostate, and of the pelvic floor muscles. Anal masturbation can be especially pleasurable for men because it often stimulates the prostate, which also contains sensitive nerve endings, and for women because it indirectly stimulates the G-Spot, clitoral legs, or the cervix.〔See (page 3 ) for women preferring anal to vaginal, and (page 15 ) for reaching orgasm through indirect stimulation of the G-Spot. 〕 Some butt plugs for men are specifically shaped for prostate stimulation. Since the muscles of the anus contract during orgasm, the presence of an object holding the sphincter open can strengthen the sensation of the contractions and intensify orgasm. Some men find the quality of their orgasm to be significantly enhanced by the use of a butt plug or other anally inserted item during intercourse. At the point of orgasm, the stretching of the sphincter muscle and pressure on the prostate strengthens the sensation of contraction in much the same way as mentioned above, for females. It is not uncommon for a male to achieve orgasm through anal-prostate stimulation alone.
Enemas or anal douches can, for hygienic reasons, be taken prior to anal masturbation if desired, but they can also be a form of anal masturbation themselves: see klismaphilia.
Commonly inserted objects include butt plugs, anal beads, dildos, vibrators and fingers.
