Anal sex is a form of sexual activity practiced by people who suffer from obsessive-compulsive disorder (OCD).
It generally resembles normal sexual activity in that tab A goes energetically into slot B, but the participants mutually consent to keep it as sanitary and orderly as possible. The term is derived from the English words “anal”, meaning “obsessive attention to detail”, and “sex”, meaning “hard fucking.”
Anal sex is characterized by several factors that are rather unique to sex, such as orderliness and sobriety. Because anal sex differs somewhat from the sexual norm, it is a less universally accepted and even controversial form of sexual activity.
The practice also stems from the natural human curiosity for the other hole; an ancient Greek proverb explains Thy dick is not for vaginal sex, or it would have been formed in the image of an axe.
