I would preface my remarks by first saying I am strong advocate that each lady should only do those activities she is comfortable with, risk wise. That said, I always have trouble with SF Chart in that it cites the risk but does not give any information about the magnitude or the comparative nature of the risk for one to make an informed decision.  For example, Hep A and Shigella are a consequence of ingesting human fecal material.  It is surprising to me how many ladies that insist on CBJ also lick the client balls which are much closer to the anus.  This risk can be minimized if the lady insures the area is thoroughly washed before the activity.  Most Shigella and HepA infections occur by ingesting fecal contaminated food.  In develop countries 50% of the adult population has antibodies to Hep A indicating prior exposure. There is a vaccine for Hep B and all working ladies should get it. The oral cavity is an inhospitable environment for gonorrhea and Chlamydia and only rarely colonized the pharynx and compared to the same infection in the genital area is usually benign unless your are immuno-compromise.  Most of us are infected with the oral herpes virus which offers some protection against re-infection with genital herpes.  Clinically genital herpes and oral herpes are the same and re-occurrence of genital herpes infection orally is rare. The HIV risk from oral sex, especially without CIM is similar to the HIV risk from protected vaginal sex assuming a 90% protection factor for condoms.  Even with vaginal sex HIV infection risk is very low compared to the risk of other STD infections.  For example the risk is 1/500-1/1000 for unprotected vaginal sex with a known HIV partner.  The oral risk is estimated to 10 to 20 times less.
