What exactly is a gape?

A gape is essentially an opening in the anus. This is usually caused by an extended period of anal sex, giving the muscles enough time to get used to being open, and remain open when the penis or sex toy is removed. It isn’t necessarily done in a violent or nasty way, although it might look like that in some porn movies. Gaping is simply another aspect of sex that some enjoy, and others will find quite strange.
