I found a link that says that it is an extremely low risk via sexual fluids, is that still valid amongst the pros on this forum?

Saliva will not kill the hepatitis C virus. However, HCV is not found in infectious amounts in sexual body fluids the way it is in HIV or HBV. HCV is a blood borne pathogen. Blood must be shared to transmit the virus.
Just because the virus us not transmitted in vaginal fluids, it is transmitted in blood, (blood to blood contact) so rough sex which creates tears, etc., can transmit it. The best thing is NOT to have rough sex and TO practice safe sex in casual encounters. That is not bad advice in any situation. In monogamous situations, especially long term ones, doctors do not even recommend protection and there is usually no risk there.
Good luck.
