From what I heard from a doctor in another forum, the health risks are the same pretty much as regular anal. Nothing big really. Apparently the body has to get used to the bacteria from the other person so they don’t get ill. ATM, has particles of feces I’m sure, but not like if you were going to actually eat feces. Feces is a waste product as we all know, so there would be no nutritional value to it, making it the reason why people get sick. Dogs eat their poop all the time and it doesn’t harm them.
I’m not saying I do this, because I don’t, I’m just explaining the risks and sharing the information as I’ve read from different places. Plus, we are constantly sticking things with fecal particles in our mouths. Our toothbrushes and even other things in the bathroom area. When we poop and fart we release particles into the air and they settle on everything. Also if you don’t put the lid down before you flush it will also send everything into the air.
ATM health breakdown
I also saw this bit of info on another site:
“For a matter of fact the rectum of a person with a healthy digestion contains only traces of feces which contain much less bacteria then your fingers after opening a public door and even more less then your fingers after operating a keyboard of a public or semi-public computer. And those bacteria in feces are natural to the body – something what cannot be told about those on the keyboard etc.
For this reason sexual practices like described before are for sure a question of taste (again sorry for the pun but actually TRACES of feces are odor and tasteless by definition) but not of health.
The myth of human feces being so very poisonous/dangerous is probably derived from the Vietnam war where the Vietcong used to smear feces onto the spikes of man-traps to further infection (and for the humilating properties). But it´s not fresh feces being so dangerous but about any organic matter becomes infectious in the dschungle inbetween hours.”

Seems like it’s the basic risk of getting E.Coli.
