My ob gyn told me that since it is presumed that both my and my fiance' have the high risk type we are safe doing any sexual act, provided that we are monogamous, because the same strain (16- 18) does not transmit again to the same person ! Is she right? What to believe?
Yes...you can continue to have sexual intercourse and can't continue to ping pong it back and forth. This however is regarding the virus being in your genital region. Transference from genitals to the oral region is still being researched although the common belief is that the risk is still low but it can't be ruled out. So if you feel more comfortable, you can certainly use a form of barrier protection.
Fredo, this brings up an interesting question. Does barrier protection need to be used for both partners if only one of them is diagnosed with high risk HPV? Assuming both partners share the same strain, but only one of them is being treated (obviously the female partner), it seems extreme to have to go years with either no oral sex or with barrier protection. Also, it strikes me that most women with high risk HPV are not told exactly what strain they have. Should women be pushing their doctors more to provide this information since the head and neck cancers are associated with HPV 16.
