The advice is written by Terrence Higgins Trust, so I imagine is probably aimed at gay men having hook ups. Hook ups will still happen, so harm minimisation is over. This is pretty tame for gay sexual health messages, to be honest.
It is not suggesting that you wear a mask with your long term partner. It is not that ridiculous. It comes from a long history of harm minimisation in sexual health messaging where people know that people will have risky sex and try and make it a bit less risky.
Yes, this. THT promotes itself as a “sex positive” organisation and is, somehow, trying to say still have sex, but do it as safely as possible

.
It is aimed at anyone though and relevant to all. I’ve been reading the response tweets to the article - a couple made me laugh:
1. Face down, ass up...stay safe ladies...
2. ”That’s not to say sex is off the table, but should ideally be with people who are part of your household”
Some awkward discussions at the family dinner table
I’ve also seen some “Covid friendly” sex positions somewhere, but can’t find them 🙁.
Serious note though - where the article misses the emphasis is in the last paragraph and relates back to previous articles promoting the end of new HIV transmissions by 2030 - something the government’s committed to. Now is the perfect opportunity to test. They missed a trick here in promoting their new free HIV online test finder test.tht.org.uk/breakthechain
For reference, a third of people with HIV in the U.K. are women, me included, and just under half of late diagnoses are women. Don’t know the exact stats but last I saw about 8,000 people in the U.K. are living unknowingly with HIV. Shame this wasn’t mentioned more.
