The studies represent serodiscordant couples over 10 and 15 year study not one contracted HIV from oral sex..
Many thanks.
Am I correct in interpreting your comments about these studies that the incidence of HIV infection from oral sex (fellatio) in male couples where one is HIV+ and the other is HIV- is extremely low or non-existent? I just want to properly represent what you intended.
