I never had sexual relation except my husband then y doc has done HPV TEST ON ME?

There is nothing wrong with being checked for HPV. Men are considered carriers of the infection and there is not reliable test to do in testing men for it.
It's much easier to test females and it is a routine check when you go in for your yearly exam as long as your sexually active. It doesn't mean your husband cheated or you cheated; in fact, HPV can stay dormant (even from testing) in your system for months and years.
My mother was tested for HPV after my sister was born and was positive but only was with my father (who was faithful too). It just happens, it's very common and there is at least 100 strains of HPV out there. 6 of them are known to be high risk and possible move onto cervical cancer and 30 of them are known to cause gential warts.
Even if you do have it, sometimes your body can actually fight off the infection and then that strain of HPV will be gone from your system.

Good Luck!

1) your husband may have had other sexual relations, and a very high percentage of the population carries hpv. plus you can get it other ways than sex

2) people lie about their sexual history all the time so they do it to everyone

TO KNOW IF YOU HAVE CERVICAL CANCER.. CERVICAL CANCER IS NOT ONLY CAUSED BY HAVING SEXUAL RELATION TO OTHER BUT ALSO IT IS CAUSED WHEN YOU HAVE LOW IMMUNE SYSTEM

HIV can spread through other sources like, blood transfusion, infected syringe, Tatoo Needle etc.

Men can be infected through Razors from Hair Cut shops also.

There is need to worry just for testing. Every pregnant woman and every TB patients are tested for HIV.
Testing for HIV is no insult. In fact it is good to know the status.

Last month I was asked by my doctor to get HIV test along with other blood test, because I was having stomach pain and loss of weight. I am a virgin. Still I don't have any objection. It has become a common test now, and it is not very expensive.
It is caution is better than doubt and panic.

one of the ways HPV can be cought is sex but there r other ways too. that dont involve sexual actions.. you can get it from tryin on a bathin suit that someone else has tryed on and they have HPV and BAM you have it too..
