It was 6 years ago 

And never I had any symptoms 

Is that right? 

You have correctly answered your own question. HPV transmission by oral sex certainly is rare. There are no data on just how high the risk might be. However, even among the most sexually active persons, the large majority do not have active (transmissible) oral infections, and therefore most oral sex exposures are zero risk. So is it possible? Yes. Is it likely? No; any particular exposure is nearly zero risk.

Let me know if anything isn't clear.

Why a lot of dr they are saying if someone touch your penis you may get hpv and other drs saying no risk at all 

Merely touching the penis does not transmit HPV. The "someone" who says there is risk doesn't know the facts or is deliberately untruthful. (It's a common problem in some cultures, e.g. when non-scientists and non-phyisicans -- and sometimes religious leaders -- are a common source of information about sexual health and STIs. It's world wide problem, although more common in some cultures than others.)

Is the nose warts common as the oral warts ?  ? 

That completes this thread. Please note that repeated questions of the same type are discouraged. This being your second about zero risk situations for HPV, it probably should be your last. Please feel free to return when you start having realistic risks for HPV or other STIs.

I hope the two discussions have been helpful. Best wishes.
