Fisting fisting is a sexual practice offered by some of the ladies at an escort in Berlin. During fisting, fisting, one or two hands are inserted into the vagina or anus. There are different variations of this sexual practice: vaginal fisting / insertion into the vagina, anal fisting / insertion into the anus, double fisting / insertion of two hands into the vagina or anus and self-fisting / insertion of the own hand for masturbation. From an anatomical point of view, the vagina is very flexible during fisting, so this type of exercise can be performed regardless of age and body stature, however, one should approach such a practice with caution in order to avoid injury to the sensitive mucous membranes. With anal fisting it is even more difficult because the anus is even less stretchy. In both cases, mutual trust and the slow approach with a few fingers is recommended. The use of lubricant facilitates insertion and also reduces the risk of infection.
