No, it just means that he's been intimate with someone else at some point or other in his life.
HPV can be around for years, so it's no way to determine fidelity - unless you both were claiming to have had zero contact with anyone - EVER - then it would maybe raise an eyebrow.
It doesn't mean he had to have had sexual intercourse. It means he (or you, I don't know) could have had some sexual encounter where genital skin and genital skin came into contact (vulva, vagina, cervix, penis, anus/rectum, mouth/throat) with someone who had a strain of HPV).
