He stinks

HELLLLP. My boyfriend does not make it a priority to shower at all. I made him shower with me daily while I was pregnant but now since it's up to him to shower he chooses not to. Idk if he thinks since he doesnt do much getting dirty at work he's okay or what. It's making me lose interest which I don't want. I can't even love on him How I want to because it's been days since he's showered. How do I come about bringing it up to him in a good approach???
