In my youth, when I was living in San Diego, it was a coin flip. Now that I am older, the hole has to be clean, no if's and or buts. When I bottom, I make sure that I am cleaned out. And as I am getting into fisting, I am even more intent on such. Not scene shamming, however, there are reasons for both. As a bottom, I clean out cause after a top is done fucking me, as the bottom/sub, to thank the top, one should suck the tops cock clean. And it would be awfully awkward if the cock is filthy. Not to mention that some dom/tops would force the issue, so not a good thing. As a top, one if it is dirty, play is over. The biggest reason is that I have gotten a UTI from a filthy ass before and I am not going through that again. And for fisting, as many like the skin on skin contact, well lets just say if the ass is filthy, nothing ruins a relationship between fister and fistee, than say the fister having to go to the hospital for an internal infection, putting him out of commission from playing or doing his favorite activity.
