Is it possible for my girlfriend to acquire hepa B virus from me through french kissing only?

Answer 1

In theory, because the virus is present in blood and saliva, and people often have sores in their mouths or bleed after brushing their teeth. In the real world it may not happen.

Your girlfriend should get vaccinated anyway.

Answer 2

You definitely need to research that one bro, a lot of std's can be spread by kissing... syphillis for example. check webmd.com, cdc.gov.
