I've posted about this in "Our Stories" -- my first inkling that my husband had cheated on me, was twelve years into the marriage when he called me in the middle of the night, on my 50th birthday, crying because he'd tested positive, twice, for HIV. His cover story: that he'd gotten it from a dirty needle in a rural clinic in the third world, long before we met. That meant he was telling me he'd been positive while we were still sexually active, and when we were trying to conceive our daughter, which was before I carried that pregnancy to term, delivered via C-section, and nursed her for the first year of her life.
So I had a pretty rough few days there, and I spent a lot of time online trying to figure out what the transmission rates were for heterosexuals. Interestingly: it's not that "gay" sex was riskier than "straight" sex. The statistics don't show that, if you count women. For women, it's gay sex that's safer than straight sex.
The statistics really showed that people of either sex who have sex with men, are at significantly greater risk than people of either sex who have sex with women. I'm trying to figure out what the truth is about monkeypox, because there are mixed messages about whether it's a similar issue. Married women who don't know that their husbands are cheating, are at risk, perhaps even moreso than gay men who know what the risk is.
