1) the risk is thought to be around 20-40 percent chance per exposure but it’s not well studied on oral sex
2) the virus only enters where it made skin to skin contact. It won’t enter your throat and infect your genitals or vice versa. Although there is some interesting studies on HPV causing most cancers like breast and lung etc.
3) no, most infections clear in two years or less. Males seem to clear infections quicker. Chances even if you have a high risk strain that it will clear and will be no issue. Almost everyone in the world has or has had some form of HPV in there lives.
I am gonna say very low risk.
Practically there is no risk
Theoretically, it has risk. Ur mouth is still lined with mucous membrane
