Anal
Anal sex is one of the most taboo forms of sexual play commonly practiced. Long a source of societal shame and discomfort, many people feel the anus is off-limits so it's embarrassing for some people to admit they like having their anus touched or stimulated. But there's really no reason to be embarrassed; anal play has long been a part of sexual practice for over a third of Americans, including homosexual and heterosexual men and women, both partnered and alone.
Most people don't realize that anal intercourse is the least practiced form of anal play; stimulation with fingers, toys and tongues is far more common, partly because the prostate, the rectum and the rim of the anus are all rich sources of nerve endings. Gentle stimulation of these areas can be very pleasurable.
