[sci.med.aids] How `safe' is getting a blowjob?

hnewstrom@x102a.harris-atd.com (Harvey Newstrom) (11/18/89)

I have a friend who gets blowjobs from strangers.  He claims that this is
perfectly safe, as there has been no documented cases of AIDS transmission
via oral sex.  

Can someone send me references to studies on the transmission of AIDS via 
orals sex.  Specifically note any `proven' cases.  I am really worried 
about my friend's behavior.

Thanks.
