Um....we have been an active anal play couple for decades and we have never....let me repeat that....never had any soiling of toys, fingers, penis..ever. Not once, not ever. As for gas...never had any expulsion of gas during anal play beyond some release of air after he has been pumping me, piston style for a while. Neither of us finds it an issue, since if he fills me up like a balloon with air, it is going to come back out. It isn't really a "fart" (I hate that crude word), and doesn't have much in the way of odor, since it really isn't intestinal gas, but air that has been forced in. These issues should not deter you from anal play, if you are interested in it. less
