Hookup questions

Hi everyone, so I just hooked up with this dude few hours ago, we didn't cum because i told him to stopped when we did anal because it hurt really bad. We used condom. However I gave him a few second blow job and his precum came out and I think I swallow a tiny bit of it. Now I'm really scared. He said he's cleaned and recently just got a new job so I'm sure they gave him a drug-test (not sure if they can show std/hiv or not). Please let me know your thought. I'm a bit worry.
