Yes, I would say its normal, because everytime after I do it, I have the urge to poo, and if there is somethin in there to poo, I will, but I like to plan it out to where I have gone "number 2" the day before, so its nice and cleaned out; I find if I poo the same day I have anal its too sore, but depends on your bowel movements and stuff. Just be sure in the future to be cleaned out before you do somethin like that, and even if im cleaned out when I do it, there still is a smell, and probably some on his penis. What do you expect though?! Its ment to be an exit not entrance...And I dont do it often, it is good 'period sex' though, haha.
