My boyfriend never gets jealous, not even a bit, is that normal?

Hi all.. some will say what's the problem with that? But the thing is I find it very cute and also hot if I see my man jealous.. and not the toxic part, like clingy you know.. but no matter what happens or whatever men will do to me he doesn't show any emotion at all almost like he doesn't care..
