my girlfriend and i have been together for a long time and we had sex around 100 times and we were discussing about trying anal. so i tried first shoving my index finger into her anus and i couldn't get it too deep cause i was scared that there might be shit in there and getting shit into ur fingers ain't so romantic. soo we decided to put myself a nice condom and just go ahead with the anal. its our first time and do you think it'll be ok? anything else i should do so everything will go smoothly (ahaha pun). many thanks.
There usually isn't much if any shit in there, but it's something you have to not worry about if you want to fuck her ass. Other than that if she has a nice high fiber diet including psyllium husk that will clear her out really good.
