Anal stretching is a sexual activity that involves stretching the anus using fingers or fists, butt plugs, dildos, or other tools.
Anal stretching may be undertaken as part of slave training or for isolated sexual pleasure. It can be undertaken alone or with a trusted partner. Anal stretching makes various anal activities, like anal sex and anal fisting, easier.
Anal stretching can feel slightly uncomfortable, yet intensely pleasurable. It should not be painful, although the sensations can take some getting used to. If the anus bleeds, you should stop your anal stretching session and go more slowly next time.
The anus will take three to six hours to return to normal after an anal stretching session. Rest your body for two to three days before trying anal stretching again.
While some people insist anal stretching is totally safe, scientific evidence suggests that severe anal stretching can damage the sphincter muscles.
