Can you still get papiloma virus even in a monogamous relationship? or can you just get that when you have multiple sex partners?

(1) Yes, (2) No: Yes, a person can get human papilloma virus from one other person, if the other person has the virus. No, a person doesn't need multiple partners to get hpv. For example, a person with 5 partners over the years, won't get hpv from any of them if the 5 did not have hpv. This is one reason all non-sexually-active teen girls should be vaccinated (in case their future husbands have hpv).
