Rim Me

I say, “go for it.”  If you haven’t had the problem so far, with your current and past lovers all busily licking your ass in the “wrong” direction, you’re probably doing a good job of washing up first.  It seems to me that if it’s clean enough for a non-scatophile to happily lick, it’s probably pretty clean, and your experience bears out that this seems to be a low risk activity for you.

But the textbook answer to this question is that, yes, it is possible to push tiny (invisible) bacteria along with your tongue and then drop them in the opening of the urethra, thus creating step one for a UTI.  Step two is that the bacteria gets pushed farther up the urethra, which when it happens, is usually a side effect of hard fucking.  The urethra doesn’t have sucking action, so cooties have to be pushed in.

One of the best preventatives for UTIs is to pee immediately after fucking, which helps wash any errant bacteria away before they make you sick.  You could customize this procedure by peeing after the analingus and before the hard fucking, if your cupcake wants to take that extra precaution.
