It really doesn't, muscles can be stretched and they can recover back to normal quite easily
Do you think bodybuilders stay ripped forever?
Forcing muscles to stay in non-natural position takes a lot of time, practice / routine
Assplay on it's own it's going to stretch it 1. regularly enough 2. long enough 3. widely enough for "shitting" to become a problem, since your sphincter will be in regular position the other 23 hours +/- per day
The only people who have "troubles" are people who are willingly doing it to themselves with massive sizes or are naturally predisposed to it
