I knew a guy that was really into his hookers from sex worker sites and the prices he’d say were shockingly cheap. He got regularly checked out, and after years of doing this (at least 5) the guy says the only STD he’s ever got was chlamydia, which was in his “pre-hooker days”.
That’s all to say that you’re probably fine, but you should definitely get tested for peace of mind. If they’re sex workers by trade, they’re probably on top of the testing themselves.
Let people like what they like, whether it’s looking at girls online, cosplay, sports, or being an insufferable cunt on social media.
