1. It is possible you infected him even with a condom. Straight men have gotten HPV warts in their anus without ever having sex back there.
2. People with compromised immune system have a very tough time clearing warts. So do pregnant women who have weaker immune systems.
Yes apperantly it is possible even with a condom if the affected skin is not covered by a condom. It could have been from someone else previously, depending, it’s really hard to tell. I was with someone who didn’t have hpv then was taken advantage of by someone who didn’t wear a condom and ever since I’ve had itching vagina and has moved to my anus aswell, Ive got high risk hpv but I’m also worried it’s possible to get warts from the itching as that’s the only thing not ruled out which must be causing the itch/burning. I don’t have any visible to the eye warts but I itch like crazy and even in my anus area, I’m a straight female and never had anal sex. I could get Anal cancer from the high risk hpv just from the affected skin areas. Hpv sucks, depending what strain. I don’t even know what strain I have. I’m pregnant right now so I’m extra worried about clearance and imuumne system, as with hiv infected, they do say it’s a lot harder for the body to clear hpv strains. I do know from others who aren’t immune compromised that don’t clear certain strains, some strains are for life and very hard to clear. Sorry if that doesn’t help, that’s just from other people I’ve heard, frustrated about having hpv for 10lpus Years. Let’s hope we can clear our strains and your partner can clear his despite being immune compromised. I don’t know much about hiv and hpv clearance, I’ve only heard it’s harder to clear with hiv
