I care whatother folks because they will waste public funds to treating their anal cancers or from chemical poisons melt into their rectums released from anal toys. I am anal expert.
It is only what you make it. If YOU think it's dirty than yes, it's dirty for YOU but it will NEVER be prohibited by law - good luck on that one, there are many other things like alcohol that should be banned first sweetie.
Receive anal sex will have a great chance to be infection of H. Pylori, which will cause stomach cancer because H. Pylori will be found in the stool. The movement of anal sex will cause broken tissue there and H. Pylori will enter into blood.
If you are doing anal then you know or should know the dangers before, if not then you are not prepared are not sexually mature enough to be having sexual intercourse at all. If you are having anal sex and get these infections/cancers (which are rare) then you have not cleaned before sex and it is your own fault, just like any STD's with sex into the VAGINA which could be any variety of STD.
But animals dont have anal sex? Also ANAL CANCER LOL XD
I had heliobacter pylori 8 years ago. I have taken pre-pack for two weeks to kill it. most Chinese have heliobacter pylori so that I will not shop at Chinese supermarkets or eat at Chinese resturants. What happened if people make food who have fungers or black nail fingers. The fungers will enter your stomach? It is hard to kill finger's fungers How to kill fugers at yopur stomach? terrible.
