hpv is contracted through skin on skin contact the best thing i could tell you about oral sex is that it is very contagious i grew a wart on my leg where it transmitted from my crotch to exactly where it met my leg i became angry and cut the wart from my leg bad chioce i know :)
If you got the DNA test and they told you you have HPV 16, you have to be careful because it is one of the causes of oral cancer. However, it doesn't mean you have it in your mouth yet. Tell your doctor about it and check every change in your mouth, specially if you have some bruises or injuries that don't heal. Be careful transmiting the HPV to any women. I know sex is the best in the world but women get more serious problems than men when they have HPV. Good luck!
