Mmm, yes. Nothing quite beats sticking your tongue into a beat up trash compactor and feeling internal hemorrhoids, eh? And, if you're really lucky, you might catch her with a flareup of external ones. They must be deliciously juicy, especially when you bite them.
I'll stick with women who don't do anal, thanks. They're less likely to develop butt berries, among other nasties. And their buttholes, if they're decent looking, are much more likely to stay that way.
