I am training for wider size,, and therefore I Like to keep the shaft in for longer times, not so much the plug as it is narrow at the base to stay in. My intention is to stretch the sphincter and when I put in a plug with a narrow bas, yes it stays in, but is not going to stay wide at the sphincter, I hope I can explain myself correct.
The toys I like to keep in is this kind:

Although since the day I started this post, I have succeeded in wider sizes, so I can now easily insert this one:

And obviously due to the big head she will not come out, unless I walk around the room and shake my butt. 😃
I have now reached this size: 😃

And this will stay inside of course, since it has a great bottom part.
Again its the stretching / training I am after of the sphincter not the rectum.
