Im okay right?

I take the birth control pill daily. I had sex and he used a condom and did not cum. He did touch me down there after he took the condom off but if anything could have got on his hand like precum the air would have killed it right? Is there any advice on how to stop overthinking something going wrong when there is basically no chance of anything going wrong. I have noticed everytime I do something with a guy I over think something can go wrong when nothing can because of all the precautions taken.
