Seriously though, a lot of STD's are hard to catch through oral sex.  We've talked about this before, but there hasn't been a documented case of AIDS being contracted through a blowjob.  Some may argue that point, but the odds, while they may not be zero, are minicule.

Conducted studies do  not rule out the possibility of transmission of the HIV virus thru oral sex.  Theorectically it is possible, however it is  unlikely.  HIV highest concentration is in blood and semen.  It is more likely that the female could contact HIV thru oral sex given to a male than vice versa.  The virus is present in vaginal secretions, but not at a high concentration as in blood and semen.  In fact, CDC advises that saran wrap( this must feel great), or a dental rubber dam be used when DATY,  hope no one has suffocated lately. The virus has also been dectected in saliva, but at very low concentration levels.  The virus is extremely fragile when exposed to air.  DFK is also a theorectical risk, but once again highly unlikely.  If the virus was so easily passed thru DFK we would see dramatically more cases.
