Vaginal intercourse was practiced more than insertive anal intercourse among men, but 13% to 15% of men aged 25 to 49 practiced insertive anal intercourse.
Men may also enjoy the penetrative role during anal sex because of its association with dominance, because it is made more alluring by a female partner or society in general insisting that it is forbidden, or because it presents an additional option for penetration.
While some women find being a receptive partner during anal intercourse painful or uncomfortable, or only engage in the act to please a male sexual partner, other women find the activity pleasurable or prefer it to vaginal intercourse.
As with most forms of sexual activity, anal sex participants risk contracting sexually transmitted infections (STIs/STDs).
Anal sex is considered a high-risk sexual practice because of the vulnerability of the anus and rectum.
Researchers say adequate application of a personal lubricant, relaxation, and communication between sexual partners are crucial to avoid pain or damage to the anus or rectum.
The anal sphincters are usually tighter than the pelvic muscles of the vagina, which can enhance the sexual pleasure for the inserting male during male-to-female anal intercourse because of the pressure applied to the penis.
In pornography, anal sex is commonly portrayed as a desirable, painless routine that does not require personal lubricant; this can result in couples performing anal sex without care, and men and women believing that it is unusual for women, as receptive partners, to find discomfort or pain instead of pleasure from the activity.
By contrast, each person's sphincter muscles react to penetration differently, the anal sphincters have tissues that are more prone to tearing, and the anus and rectum do not provide lubrication for sexual penetration like the vagina does.
The likelihood of pregnancy occurring during anal sex is greatly reduced, as anal sex alone cannot lead to pregnancy unless sperm is somehow transported to the vaginal opening.
Because of this, some couples practice anal intercourse as a form of contraception, often in the absence of a condom.
sources sometimes use the term anal intercourse to refer exclusively to penile-anal penetration, and anal sex to refer to any form of anal sexual activity, especially between pairings as opposed to anal masturbation.Tags: Adult Dating, affair dating, sex dating
