I think statistically the health stat's of sex worker in both countries are similar?
CBF checking though
I think the checking thing comes from the fact they have many more travellers in Aus so are more vigilant. How successful it is would be moot; many STD's are asymptomatic or not visible.
I think paid sex is pretty low risk, casual sex from app hookups or drunk party/festival/clubs is higher.
I'm more worried about catching a cold/flu/covid and having to put up with it for a week or 2!
It does amuse me to hear some friends being all paranoid about 'getting bugs' from touching a toilet door handle or going to a mall.
Meanwhile, I'm thinking: Mate, yesterday I had my face buried in a strange girls intimate parts and was licking her ass. And loving it!
