People that identify as gay or bisexual have better STD testing routines.
All groups have better STD testing routines and preemptive measures than before.
Gay and bisexual groups have better results by being more proactive.
No new risker behavior is being seen as more prevalent from this data, in the UK.
The end result: historically at-risk populations have HIV more-or-less under control, while populations that historically have considered it a non-or-low risk (heterosexuals) don't. It has nothing in particular to do with sex acts.
seems a possibility
Sexually active gay men generally take PrEP.
Men who have sex with men are a tiny proportion of the population so the effective rate of infection is still (as we've known for four decades) far higher in these people.
They also don't account for other key risk factors: IV drug abuse, increased immigration from high incidence populations such as Africa and heterosexual woman who have sex with bisexual men.
Apparently understanding numbers and statistics is too hard for people trying hard to fit facts to woke narratives.
