CIM?  Compared to using it as lube for anal sex.  Just mix in a little common sense here.  I'd say both have risk. What I have read is the virus does not live in Saliva, so it may be a safer bet for CIM?  Again, no Dr. here.  But LUBE, thats wacked.  If you read up on any site, STD's are spread through anal sex the easiest because blood vessles are right at the surface.  You expose one of those due to rough sex combined with a little cum from an infected partner for lube, yea, I'd say the chances go up.  I would not want to find out, thats for sure.
