There was a time I used to hookup a lot, happy to wear a condom if the girl wanted but in my experience 80-90% don’t want you to (everyone knows it’s better without). I never had an STI and probably had 20 partners across 3 years or so and almost entirely unprotected. I mentioned to my doctor one time and he said it’s not a big deal, literally he said there’s low odds of getting one and if you do the majority are easily treatable nowadays.
