Thanks
To explain.........
Did you share a syringe with a fellow drug user? If so, that's a high risk exposure.
The reason the virus can remain active in a drug sharing exposure is because the blood inside of the syringe is not exposed to the elements, and when the second person uses the syringe, they inject the contents (including the blood from the last user) directly into their bloodstream.
Oral sex was a different concern
This is pertaining to used syringe
What does that have to do with your oral sex issue.
