I forgot to write ... there is research to suggest that when infection of the membrane of the mouth occurs, and it is not "massaged" through friction when the virus can infect only the upper layer of the membrane, also induces an immune response and virsuet fought normal, but the reaction is not as strong as if the virus infects through wounds, etc., because the body does not get immune to the infected HPV variant without infection can occur again and again with the same virus.

That would explain a lot of differences between man o woman, the woman create a lasting immunrespins by the virus penetrates further down, perhaps in the mouth but mostly in the vagina and then the woman is immune.

Conclusion better to get a big infection than many small ... just as in the case of the common cold
