It's not the most hygienic sexual practice... so, it does have its health risks.
Hey, just dont go from the anal to the vagina, but i agree its probably not the most hygienic, but lots of people enjoy it
You run the risk of internal damage to organs/body parts inside the anus not to mention bacteria that are present..I look at it this way...if the anus was mean for sexual activity one would not have to worry about injury to those body parts, utilize artificial lubrication and lots of it, and the anus would expand naturally to accept an erect penis of any size.
My opinion of course, but I believe it was meant strictly as an "exit" organ and not a sexual organ. The frequency of reports of women reported extended periods of bleeding after anal sex is enough to give me thought as to it's health concerns.
