If a woman has a high risk hpv virus in her mouth after a small amount of woman's saliva is rubbed on the man's fingers does the man have a high risk of contracting the hpv virus by touching his penis with those fingers?

HPV is rarely transmitted by oral sex. Even if such a partner has oral infection, the contacts described are no risk at all. Of course you are going to have HPV someday, maybe already do: all human beings get genital HPV. Rather than trying to prevent it entirely, get vaccinated to prevent infection with the HPV types that cause 90% of cancers or warts. Then don't worry about it.
