Would it be ridiculous to ask the guy I’m casually dating to only have sex with me until he moves?

So I’ve been seeing this guy for a few months now. He’s at a point in his life where his career is up in the air so we’ve both understood that we can’t be serious until he figures out if he’s staying or leaving for work. He may be leaving at the end of summer. We consider us dating. We have amazing sex, like the best we’ve both had. We’re so compatible and he has said this to me. I know he’s still on a dating app and with everyone getting vaccinated... I don’t know where he’s at with this but I don’t want him sleeping with anyone else. I don’t want to be serious and say we’re a couple but I personally don’t enjoy sex if I know he’s sleeping with other women. I’m not trying to make it into something but I genuinely don’t want to share the person I’m sleeping with sexually, not to mention STDs are a scare and I give him head condom free currently.
Is this a reasonable question to ask him? I’m not setting high expectations am I?
