If I have a long anal session once every two weeks, do you think I can progress in size and depth?

Right now I can do fisting without much warm-up, I'm not a novice let's say. I don't have much time and I don't know if just 5/10 minutes two or three days a week would help.

Slow and steady wins the race. Since starting a daily routine, I’m now able to take some toys that I had put away since they were too big as my mid session toys and now invested in bigger toys because of it.

 

For example, the XL Diego toy from BadDragon, a year ago, the knot was impossible for me to take. Nowadays, after 10 minutes, I can ride it and sit on it for the knot to pop in.
