Well, I am sure it depends on the woman, BUT, when one engages in anal sex, there are some safety precautions. The anus and rectum have some very nasty bacteria in them. Washing, bathing certainly help, but some of it is internal, and even enemas won't rid the rectum of all bacteria (and for the woman's health, which this bacteria is needed THERE, you wouldn't want to)
"Ass to mouth" can cause some serious gastrointestinal infections. Usually similar to the "tummy flu." (sometimes worse, depending on the bacteria, the strain and the receiver's immune system.) Before My Man and I learned all the ins and outs (sorry) of how to have sanitary Anal, I got a few nasty UTIs and vaginal infections from cross contamination, and My Man got very sick for about two days, which may have been food poisoning, but I am almost sure it was from our not being careful in that area. My Man and I only use anal last, or if we decide to revisit intercourse or a blow job after we have started anal sex, we always wash him with a wet warm washcloth, with clean rinsing soap, and clean his penis carefully before it goes anywhere else. All fantasies aside, it really is less than healthy to practice ATM, (I am far from being judgmental, I really enjoy anal sex, I just know the score and don't like either My Man or I getting sick) but you will have to do your own research and your woman will need to decide if she wants to take the risk of a gastro intestinal infection, similar to the tummy flu, or a mean vaginal or urinary tract infection, which is a good bet for many people aren't careful about penises, fingers, dildos ect after they have been inserted into anuses and then placed elsewhere without being cleaned. Some people will use a well lubricated condom for the anal, and then quickly whip it off for some oral, and although this may still cause some bacteria to linger in some areas, is certainly safer than bare ATM. You asked if any of us "ladies" liked ATM? Me, no. Anal, sure, with My Man, but we have learned the hard way to be clean and careful.
I can be tolerant of almost anything....except Intolerance........and Dairy Products
