My girlfriend has hpv. can i get it if she use saliva as a lubricant when giving me a a handjob? also can she give me oral sex?

Possible...: While hpv infection is largely considered std, its auto-inoculation is possible, like laryngeal papilloma by maternal to neonatal route. Besides, many hpv-infected persons may have no visible warts, and not all the exposed contract it. So, it's possible; these may irk your yes-or-no expectation, but that would never be in real life. Then, keeping healthy is key to win invisible war.
