yeah but you don't drink boob milk forever. as an adult, breastmilk is bacterial warfare on your intestines. obviously literally eating stuff is disgusting and unhealthy for you, and im not saying its ok or anything. but like, if you put your tongue anywhere within a foot radius of someone's butt you're going to be ingesting microscopic feces. legs, hands, thighs, etc.
if you do brown town you're going to end up with stuff on your richard regardless of how well that person cleans. its just part of life, thats why u take a shower after that stuff
