boyfriend had hpv nearly 10 years ago

My boyfriend of 5 years just confessed to me that 10 years ago in college, he was told he had hpv and was treated for warts, but has never had any reoccurrence. Im conscious of how difficult it was for him to tell me something he found so embarrassing, but I'm very upset that after 5 years of intamcy I just found out, and am very scared at the risk I may be in. Does anyone know how likely the risks are?
