Analfucking can be really great, especially for the guy, its a lot tighter then a pussy. But there are also plenty of girls who love it and even get an orgasm from it. But you have to remember a couple a things before getting started. How is the size of the dick compared to the ass? Did we use enough lubricant? Warn your girlfriend before penetrating and dont pull back too far once you are in. Keeping this in mind there is no reason to fail like these people.
