Re: sexlife with hpv
HPV is so easily transmitted that at this point, you and your partner have already swapped strains of HPV. With HPV, sex is sex. Heck, it doesn't even have to be sexual intercourse to transmit the virus. It is transmitted by any genital skin contact with any other genital skin contact.
So, I'd say it if the two of you have had oral sex before then you aren't likely to spread or protect against the spread of any other strains of HPV (unless either of you is not monogamous).
