>>935673098To learn how to take a strapon in your ass you first buy specifically anal lube, other lube does work but isn't as recommended. When you have acquired lube you should also consider getting an anal douche to clean your insides as it can get quite disgusting if you don't.
Now that you have these items the training begins, an hour or two after shitting you can use the douche to clean inside your ass, after the douche-ing you will start with just one finger. Start by lube your finger AND around the entrance to your anus, don't make a singular small coating but instead really slather the lube on both the finger and anus, both should be dripping, now put your lubed finger in there and move it in, out, and all about. After a bit you have to take your finger out and lube it up once again as most of the lube will be inside of you now, keep fingering the lube into your ass and try to stretch the anus with that one finger so you can move up to two fingers, then maybe 3, after a while you re-start the process but with an object such as a dildo until you can take the strapon.
Remember, there is no such thing as using too much lube, the more you use the better.
