find an object you can fit in your ass relatively easy, put it in, an keep it there at all time. remove only to go to bathroom or when doing other task. something kind of "T" shaped, so it will fitin and the "T" part will prevent it to get completely in, while fiting in your "crack", not preventing you of everyday movement.
Remove for cleaning and the like, but always wear it beside of that.
you could use some kind of wood part... could found in any home renovation center, like part of ramp or the like, small pre made table leg... search a bit, you should find something.
But the idea is to always have something in your ass, 24/7, that prevent your ass to close.
Keep PERFECT hygiene tho... use condom for safety on the object...
In fact, buying a butt plug would be the best: yeah, there is the concern of the maney, but you don't have to care about where storing it: you will not have to keep it elsewhere then in your ass at all time
