Tips for Cleaning your Ass Before Anal?

I don’t have a douche or anything but I seriously want to be spotless inside because I tend to get constipated a lot and have noticed that I’ll just have poop sitting around in there pretty deep and I don’t want to have sex and have them feel my god damn poop😂

Like how does one properly clean their ass before anal so that there’s no awkward accidents... i seriously am terrified of him pulling out and it looks like we dipped his dick in a chocolate fountain😭😭 help a sister out!!
