I am a gay male on Prep. I have one sexual partner but he has others besides me. After about two months of not seeing each other, we engaged in oral-genital, oral-anal, and anal intercourse today. Both of us gave and received for all activites. Afterward, I noticed a single small white bump on his anus that seemed to have grown ON the skin (not under the skin like a Fordyce spot or hair follicle). I am worried this was a wart. Assuming it was indeed a wart, I have some questions. Am I correct that exposure to a physical wart can easily lead to HPV infection but will not necessarily lead to me also getting a physical wart myself? Or am I almost guaranteed to get physical warts if I was exposed to his physical wart. Basically, I'm not clear on how often infection with HPV results in a wart you can see, especially if the person you got it from infected you with the kind of strain that causes visible warts in the first place. And should I be worried about my performing analingus or is that an unlikely route to infection?

Thanks Doctors!
