My boyfriend doesn't like me checking out other guys?

Anonymous
FYI: I get very attracted to tanned-dark skinned guys (e. g. African guys, arab guys)
Anyway, he knows this so whenever we go out to places and if there is an African or arab guy in sight, he would always look at me and say "I saw you checking him out. Don't look at him" or "Why were you checking him out?"
Sometimes if our car is in traffic and a car pulls up beside us and there's arab guys, he would be like "Dont look that way" or he would kiss me.
Thing is though, when he says all this, he laughs. Like it seems like he's just half joking around. I don't take it serious coz I laugh it off but yeah I don't know.. it's quite odd.
Is this normal? Why does he do this?
