I am a gay male who recently met up with another man for sex. He asked me to rim him (lick his anus), but as I was doing so I noticed what appeared to be anal warts. He didn't seem to know he had them and seemed surprised when I brought it up. We had more sex (he was the penetrative partner, with condom), but now I am wondering whether there could be a chance of my having contracted HPV from his anus, assuming they were indeed anal warts? Thanks a lot.
