Hello, so here is the full story. On August 2012, a woman (about 40 years of age) had oral sex (unprotected) with me (my penis in her mouth). It happened only one time. Then on October small pimples grew on my girlfriends butt cheeks (she is 25, I ‘m 26). Last week she was tested (since the pimples never went away) and it came up as HPV positive. So the question would be: Did I get the HPV from the woman and then transmitted it to my girlfriend? My girlfriend and I had sexual intercourse unprotected on various occasions. One last thing, I can’t really remember when it happened since it was months ago and it was a onetime thing so I didn’t really pay much attention to it, but I did notice a lone pimple between my belly bottom and my penis. That would be all, as you can imagine I am very concerned. Before hand, thank you very much.
