Honestly if you are gonna be dancing and drawing attention to your ass and bending over, wherever you go (if you know prior), your best bet is to shyt before or douche/use an enema. Too many of these twerk videos/club videos showing chicks bending over with dookie stains by their a$$holes. It's really off putting.
I dont have a big ass but is it that hard to wash/wipe ya ass? Or is it that their sphincter is blown from too many backshots?
