My bf going to sleep after sex makes me feel gross

Is it wrong that I dont like that my bf goes to sleep right after we have sex? In his defense we do go at it for a while so I understand why hes tired but idk it always makes it feel like a hookup afterwards. He's hard working and ik hes normally tired so I dont like to argue with him about this but it really makes me feel sick to think about what we just did when he immediately goes to sleep.
