http://femaleanalsex.blogspot.com The Anus The anus is the external opening of the anal canal. It can be one of our most sensual erogenous zones, but it is one too often feared, forgotten, and left unexplored. It is comprised of folds of soft tissue that give it a wrinkled or puckered appearance. The area around the opening is full of hair follicles; the hair may be fine and light, coarse and dark, or somewhere in between. Everyone has hair surrounding the anus. Rich in blood vessels and nerve endings, the tissue of the anus is incredibly sensitive and responsive to touch and stimulation. Contrary to cultural mythology, with regular bathing and good personal hygiene, the anus is generally clean. The Anal Sphincters and PC Muscles Two muscles-the anal sphincters-surround the anal opening (see illus- trations 1 and 2). The external sphincter is closest to the opening. With patience and practice, you can voluntarily control the external sphincter, making it tense or relax. Imagine that you are holding something in your ass or expelling something. As you suck in and tense up or push down and release, you are exercising your external sphincter muscles. The internal sphincter is controlled by the autonomic nervous system, which controls involuntary bodily functions like your breathing rate. This muscle ordinar- ily reacts reflexively; for example, when you are ready to have a bowel movement, the internal sphincter relaxes, allowing feces to move from the rectum to the anal canal and out the anus. Because the external and the internal sphincters overlap, they often work together. Think of the sphincter muscles as the gatekeepers to your ass. If they are relaxed, ready, aroused, and content, anal penetration will be comfortable and feel good. If they are tense, tight, or not warmed up, anal penetration will be uncomfortable, painful, or downright impossible. http://erobica.com Erobica.com - Erotic Aerobics And Sexual Fitness Youtube have strict rules.
