I don’t want sex

Hey guys. I’ve been married awhile. Is it normal to be too exhausted to have sex? Because my husband will wait til I fall asleep to want sex and he get mad when I don’t want to. But I told him to stop waiting til I fall asleep when I’m up til midnight. He will go out with the guys and to the gym then wanna come home to have sex. But when he home. He do the same thing. He will be outside or inside while I’m helping the kids with homework and get ready for bed. I even say help me. He like he don’t wanna deal with homework he forgot how to do. But I tell him help them with prepping for the next day. He still don’t. So you really gonna ask me why Being tired is a excuse?!

Y’all I’m upset and don’t know how to handle it because we talked and he just says that I’m making an excuse to not have sec and that I’m always tired. So yeah. Idk what else to do. He being an ass. Comment? Questions? Advice?
