Just need some opinions!

It has been 6 years since my last sexual relationship, So Basically, I slept with this guy (he is quite a bit older, his last sexual relationship was in March and was safe) anyway me and him slept together just the once and we used protection also (I will never go bare back unless I'm in a committed relationship) but he did try and rub the tip of his dick on my clit before putting a condom on. I have random anxiety about what if I've got something now? He didn't go in or near to going in until he had a condom on.

I do think I am over reacting and I did ask him the next day if he is definitely clean, he got slightly upset by this and basically said he isn't dirty and doesn't put it around everywhere and he is fussy about who he sleeps with and he has a daughter to think of so wouldn't do that. I believe him, I've known him for a while and he is a genuine man. I do think I am over reacting.... I have had zero signs of infections or anything like that. I completely understand why he got upset, and I do think I am waayy over thinking. Can someone calm my ass down 😂
