|Anal stimulation is erotic stimulation focusing on the anus and rectum. Common methods of anal stimulation include massaging the anal opening followed by the insertion of an object or objects such as fingers, fists, phallus shaped items and a number of other specially designed “toys”.||derivative work: Tsaitgaist (talk) – Male_anatomy.png, CC BY-SA 3.0|
Not just for gay men (article)
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.
Some sex toys 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 common 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. Read entire article…

* The pelvic floor muscle layer has holes for internal passages to go through. There are two passages in men (the urethra and anus) and three passages in women (the urethra, vagina and anus). The bladder, uterus (for women), and bowel lie on the pelvic floor muscle layer.
