Y’all are gross as hell.
The reason it’s harder for men to catch HIV from women is because the skin on the penis isn’t as thin as the skin inside a vagina (or butthole

) meaning it’s less likely to tear during sex. But if you do happen to already have a small tear in the skin for whatever reason you are more likely to catch it. It’s stil harder but not
impossible and just because OP is a man having sex with a woman doesn’t mean he’s impervious to HIV.
OP it could be nothing but next time just wear a condom. I would Imagine the inconvenience of having to disclose HIV and take medication your whole life is worse than whatever inconvenience you had to go through.
