The anal canal is the terminal part of the large intestine. In humans it is approximately 2. It lies in the anal triangle of perineum in between the right and left ischioanal fossa.
The inner lining of the anal canal is the mucosa. Most anal cancers start from cells in the mucosa. Glands and ducts tubes leading from the glands are found under the mucosa.
You don't need to dig around too deep to read about someone's anal sex horror story. There are tales of peoples asses falling out, people needing adult diapers for the rest of their lives, even people dying as the result of anal sex.

One of the most popular sex positions has long been a taboo topic. We tapped an expert to get the bottom of anal sex so you can too! There's nothing like having a Sex and the City -esque chat with your friends to make you feel ahead or behind the sexual curve, particularly when that curve is the butt.

An anal abscess is an infected cavity filled with pus found near the anus or rectum. Ninety percent of abscesses are the result of an acute infection in the internal glands of the anus.

Practicing safe anal sex is not as intuitive as safe vaginal sex, so Cosmopolitan. Don't have anal sex if your anus isn't clean and your bowels are still full. Because there's less lubrication and the hole is less elastic, you're more likely to get tiny tears in your skin during anal sex, so keeping the area as clean as possible is best for preventing infections. Don't use the same condom if you switch between vaginal and anal sex.
