But one other thing - if the woman's discharge during DATY is very high, the man could easily swallow quite a bit and anything that gets into the stomach can pass into the bloodstream.
The AIDS virus is utterly destroyed by the slightest contact with gastric fluids. Saliva itself is a very inhospitable environment for the human immunodeficiency virus.
I'm not sure there is any STD that can survive the gastric acid in the stomach.
For DATY, the fluids being exchanged are saliva from the man to woman and vaginal discharge from the woman to man. From what I wrote above, the risk for the woman is low because she's receiving saliva. The risk is higher for the man because the concentration of HIV is higher in vaginal discharge.
If the man has no cuts in his mouth, the possibility of HIV infection from DATY is so low as to be statistically insignificant.
With all these behaviors - DFK, DATY, BBBJ - the risk of HIV infection is extremely low. However, you want to be safe beyond a shadow of a doubt, give them all up. And since condoms have been known to break, the guy who can't countenance any risk at all would be well advised to give up covered sex with WGs as well.
