Anal masturbation

From Wikipedia, the free encyclopedia

Anal masturbation is manual erotic stimulation focusing on the anal and rectal area. 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, phalic shaped items or sex toys such as anal beads, butt plugs, dildos, a vibrator (sex toy) or specially designed prostate massagers.

[edit] Method

Anal masturbation is practiced by men and women of all sexual orientations. 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. For men, anal masturbation can be especially pleasurable because it often stimulates the prostate, which also contains sensitive nerve endings. Some butt plugs for men are specifically shaped for prostate stimulation. For women, this practice is alleged to indirectly stimulate the female prostate or clitoris. 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.^[1] 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 was as mentioned above, for females.

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. Using enemas too frequently can lead to a physical dependence on them in order to have a bowel movement, however.^[2][3]

Commonly inserted objects include butt plugs, anal beads, dildos, vibrators and fingers.

[edit] Safety

Insertion of foreign objects into the anus is not without dangers. This area is fragile, the intestinal walls don't feel pain and for objects pushed too far, surgery may be necessary for removal (even without injury). Unsafe anal masturbation methods cause harm and a potential trip to the hospital emergency room. However, anal masturbation is enjoyed in complete safety by many people by following some basic rules:

Empty the bowel before you begin. Lubricate both the anus and the object to be inserted, using a good quality sexual lubricant. Start with a small object and allow plenty of time for the anus to relax during insertion. Never force the insertion - the sphincter will open when ready. It takes time to learn to relax the sphincter muscle. Although tight at first, it can with regular practice safely accomodate objects up to 75mm thick (2 1/2 inches) - or even larger - without discomfort or injury. Indeed, many people prefer the feeling of larger objects. It is recommended not to insert any object longer than an erect penis.

[edit] Texture of insertions

Objects with rough edges can cause rectal tearing. Some inexpensive butt plugs and anal beads have seams caused by the molding process, which should be removed before use. Stimulating the rectum with a finger (for the purposes of medically stimulating a bowel movement or other reason) may allow fingernails to tear the rectum wall. For this reason, nails should be trimmed short and buffed after trimming to ensure that the trimmed edges are not sharp for those purposes. Although vegetables are not always dangerous for masturbation, many vegetables have rough edges and most have microorganisms on the surface, and could be dangerous for this reason. Some anal toys are purposely ribbed or have a wave pattern in order to enhance pleasure when they are thrust in and out, simulating intercourse.

[edit] Risks associated with bleeding

Minor injuries that cause some bleeding to the rectum pose some risk, and often should not be ignored. It is always important to stop performing anal masturbation at any sign of injury, bleeding, pain, or change in consent, in order to avoid the possibility of inflicting serious injury or aggravating a minor wound. Minor bleeding could stop of its own accord; however, individuals with clotting issues or other medical factors could face serious risk and may require medical attention.

Prolonged or heavy bleeding can indicate a life-threatening situation, as the intestinal wall can be damaged, leading to internal injury of the peritoneal cavity and peritonitis, which can be fatal. Carefully using implements without sharp edges or rough surfaces carries a lower risk of damage to the intestinal wall.

A significant risk factor associated with any injury that causes bleeding is the effect of certain drugs that cause thinning of the blood, including some analgesics or anti-inflammatory agents which are in common use such as aspirin and naproxen sodium (commonly known as Aleve). Their blood-thinning action significantly interferes with the mechanism of blood clotting which normally seals the surface of a wound and thus prevents further bleeding and makes it possible for even small injuries to bleed indefinitely. This situation is further complicated by the fact that for practical reasons, it is not possible to prevent further bleeding by bandaging a wound that occurs inside the rectum. It is therefore important to not engage oneself or others with anal masturbation, especially for the first time, until at least a week after ceasing the use of such drugs.

The treatment for persistent or heavy bleeding will require a visit to an emergency room for a sigmoidoscopy and cauterization in order to prevent further loss of blood. Apart from the volume of blood that is lost into the rectum, other easily-observable indications that medical intervention is urgently needed as a result of blood loss are an elevated heart rate, a general feeling of faintness or weakness, and a loss of pleasure from the act.

[edit] Rectal foreign bodies

Butt plugs normally have a flared base to prevent complete insertion (see also rectal foreign body) and should be carefully sanitized before and after use. Sex toys, including objects for rectal insertion, should not be shared in order to minimize the risk of disease. Objects such as lightbulbs or anything breakable such as glass or wax candles cannot safely be used in anal masturbation, as they may break or shatter, causing severely dangerous medical situations.

Some objects can become lodged above the lower colon and could be seriously difficult to remove. Such foreign bodies should not be allowed to remain in place. Medical help should be sought if the object does not emerge on its own. Immediate assistance is recommended if the object is not a proper rectal toy, like a plug or something soft, for example if it is either too hard, too large, has projections, slightly sharp edges, or if any trace of injury happens (bleeding, pain, cramps). Small objects with dimensions similar to small stools are less likely to become lodged than medium-sized or large objects as they can usually be expelled by forcing a bowel movement. It is always safest if a graspable part of the object remains outside the body.

[edit] Hygiene

The biological purpose of the anus is to expel intestinal gas and feces from the body, therefore when engaging in anal masturbation for pleasure hygiene becomes important. One may wish to cover butt plugs or other objects with a condom before insertion and then dispose of the condom afterwards to simplify cleanup. To minimize the potential transfer of germs between sexual partners there are practices of safer sex recommended by healthcare professionals. It is important to not transfer bacteria from the anus to the vagina, as infection may occur.^{[4][Need quotation on talk to verify]}
