Fact from fiction, truth from diction, many people make the mistake and think you can just jump right into it like you see in the amateur videos. The average woman who has not done it would more than not find it uncomfortable, painful, and strange. To do anal right takes time and training. You 1st need to get a butt plug or a thin anal probe. While playing with her front, you lube up the butt plug well with KY and bring it to her pink pucker. You add pressure and let is slip in gently as it wants. Forcing it will cause her to clinch and there will be pain. Once it is in, you just let it sit until she can relax with it in there and then you can ever so slowly move it back and forth. For the 1st 3 to 5 weeks that is all you do. If she is not getting any discomfort and has learned to relax, after 3 weeks you use a probe. They have many shapes and sizes and can go deeper. You always go slow with tons of lube. The last phase you want a expandable butt plug that you can pump up to near twice the size. While diddling her front to get her hot and bothered . You insert the plug. You increase the size about ½ every 15 min. When you have it expanded to about 5 to 6 inches around you lube up your dumbstick well. Quickly deflate the expandable plug and press your dumbstick to her pink pucker and allow it to swallow your dumbstick. Then you just hold there and let her buns adjust. Then you start to pump slow and long. Then you are on the way. Just remember not to go thrashing about like a shark trying to tear loose a piece of whale blubber.
