Naveed is right, mosst medical professionals agree that HPV is not transmitted as easily through oral sex. Furthermore, complications related to oral sex are also quite rare.
Warts in the throught would be more likely with fellatio than cunnilingus.
I dont know who told you that it is extremely rare! If someone has a flareup (symptoms) and rubs their warts on you, you've got them. Its as simple as that. Yes, these could go to throat and if left untreated, they cause, very often, cancer. They will have to do a surgery to remove them.
getting oral hpv with oral sex is extremely rare... you should see an ENT specialist to get good diagnoses... once you are diagnosed by your doctor you may come back to this forum to discuss the treatement options and to listen about others experiences... you should get yourself checked first...
