Answer: A small amount or none. The small amount can/could be risky. There is really no documentation on transmission from female to male. There IS documentation on a few men who have had post-coital female blood infect them via intercourse. I read that it is like males pre- cum fluids, where they have found small amounts of hiv virus in only about one-third of pre-cum samples. Are these small amounts of virus in fluids able to infect someone. It's better to use caution always when in doubt. It does seem that in dating and transmission aspects of hiv the females have been given the worst consequences in several ways.
