Cannibal boyfriend?

My boyfriend always talks about how he wants to eat me and bite me, suck my fats, cut my leg and grill it. Sending me pictures of tools to cut meat or suck fat.
Is this like a guy thing joke or what? Sometimes I get worried when he talks like that and sometimes I joke
Like when he says he wants to eat my meat I ask “No seasoning?”

Can anyone explain if this is a joke or something? Sometimes I get worried
