In general, I do not advise altering sexual plans, exposures, or practices on account of genital HPV infection, except for warts. Warts tend to have a "yuck" factor, with many people put off by them, so it often makes sense for someone with new warts to avoid sex with new partners until their warts are gone. However, for non-wart causing HPV types, I generally advise that there are no certain ways to avoid transmission other than avoiding sex entirely -- and usually sex and romance are too important to be so drastic about it. I would encourage the two of you to enter a fully expressive sex life: the determinant of your specific practices should be mutual pleasure, not prevention of HPV.

Despite your partner's lack of diagnosis or awareness of prior HPV, almost certainly he has been infected, since over 90% of sexually active people have HPV at one time or anohter, usuallly several times. Recent research shows that 50% of adults have HPV in the genital area, so there's a good bet he's already carrying it. Sex with you, even given your recent diagnosis, will not significantly raise his risk of having an HPV problem someday. Whatever HPV type you have, there's a very good chance he has already had it and is now immune to new infection with that type. (And for that same reason, couples are believed to not "ping pong" HPV back and forth. If you infect him, and your HPV then goes away, you will not re-catch it from him.)

Would oral sex reduce his risk of acquiring the particular strain(s) you have? Maybe, but not for sure. Many people with genital HPV have it in their mouths. Oral sex rarely transmits HPV, but it happens sometimes.

Be clear:  I'm not saying there is no chance your partner won't catch HPV from you. He might. However, the vast majority of HPV infections never cause symptoms, and his risk will be no higher from you than it was with his other past sex partners. He can be sure that most of them had HPV, even if never actually diagnosed. And some of those women probably were diagnosed with abnormal paps etc and didn't tell hiim.

So my advice is to discuss all this with your partner to make sure both of you mutually understand the pros and cons of unrestricted sexual expression. And most likely proceed without restriction.

I hope this information is helpful, but I understand it's a complex topic. So let me know if anything isn't clear.

Best wishes for a rewarding and romantic relationship!  HHH, MD
