Not one moment where you contemplated the risk: "maybe he will rob me in the night and leave"?

I know that risk is always there (however very low, I know that, almost non existant maybe), and I myself have boys stay overnight, but it are always boys I choose, I take the initiative (I off them or I contact them via a dating app).

In this case you were choosen by him. That is a different situation. I wouldn't be 100% comfortable from a security perspective, in such a scenario.
