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.People may experience pleasure from anal sex by stimulation of the anal nerve endings, and orgasm may be achieved through anal penetration – by indirect stimulation of the prostate in men, indirect stimulation of the clitoris or an area of the vagina (sometimes termed the G-spot) in women, and other sensory nerves (especially the pudendal nerve).As with most forms of sexual activity, anal sex participants risk contracting sexually transmitted infections (STIs/STDs).
The anal and rectal tissues are delicate and do not provide lubrication like the vagina does, so they can easily tear and permit disease transmission, especially if a personal lubricant is not used. It is controversial in various cultures, especially with regard to religious prohibitions.
This is commonly due to prohibitions against anal sex among males or teachings about the procreative purpose of sexual activity.
By contrast, people also regard anal sex as a natural and valid form of sexual activity that may be as fulfilling as other desired sexual expressions.
They may regard it as an enhancing element of their sex lives or as their primary form of sexual activity.
The internal and external sphincter muscles control the opening and closing of the anus; these muscles, which are sensitive membranes made up of many nerve endings, facilitate pleasure or pain during anal sex.
The Human Sexuality: An Encyclopedia states that "the inner third of the anal canal is less sensitive to touch than the outer two-thirds, but is more sensitive to pressure" and that "the rectum is a curved tube about eight or nine inches long and has the capacity, like the anus, to expand".
In addition to sexual penetration by the penis, people may use sex toys such as butt plugs or anal beads, engage in fingering, anilingus, pegging, anal masturbation or fisting for anal sexual activity, and different sex positions may also be included.
In a male receptive partner, being anally penetrated can produce a pleasurable sensation due to the inserted penis rubbing or brushing against the prostate (also known as the "male G-spot") through the anal wall.
Prostate stimulation can produce a "deeper" orgasm, sometimes described by men as more widespread and intense, longer-lasting, and allowing for greater feelings of ecstasy than orgasm elicited by penile stimulation only.Tags: Adult Dating, affair dating, sex dating
